So, you’ve done the deed and didn’t use protection.

Now, you’re wondering, could you be pregnant? 🤔

And, what are the chances you can be pregnant from having sex just one time?

Well, that all depends on when you had sex — more accurately, at what point during your menstrual cycle.

So, let’s jump straight into it and go through the likelihood of whether you’re pregnant or not.

In this article: 📝

Can you get pregnant after having sex once unprotected?

How likely is it to get pregnant if you have unprotected sex around your ovulation?

What should I do if I had unprotected sex, but don’t want to become pregnant?

Can you get pregnant after having sex once unprotected?

Now, it may seem like a basic question (we’ve all seen enough teen pregnancy movies to know the answer… 🍿), but it’s important to cover all grounds…

Yes — you can get pregnant after having unprotected sex one time.

But, how likely is it?

Well, that all depends on you, and the regularity of your cycle. ⏱️

To get pregnant from unprotected sex, you would have had sex around the time you ovulated.

This is when an egg is released from your fallopian tubes which, if not fertilized, will prompt the shedding of the uterus, and you’ll have your period.

But, if any sperm gets into contact with this egg during ovulation, you could become pregnant.

When would I ovulate?

You usually ovulate around the middle of your cycle — that’s roughly about 12-16 days before your period starts.

For instance, if you have a regular cycle of 28 days, you’d typically ovulate around day 14.

But, you’re most fertile during the five days before ovulation.

This is because sperm can live inside your body for up to five days (persistent little things!), so bear that in mind if you’re trying to avoid becoming pregnant.

You may notice some signs you’re ovulating too, like changes in your vaginal discharge, mild abdominal pains, or an increased sex drive.

(Basically, it’s Mother Nature’s way of saying “the egg is on the way, ladies — it’s go time! 😈”)

Ovulation can last for as little as a few minutes, or up to 48 hours — it all depends on your individual cycle.

Plot twist: you can also get pregnant after ovulation, too!

How likely is it to get pregnant if you have unprotected sex around your ovulation?

It’s tricky to put an exact figure on it, as everybody is different.

But it’s thought that if you have sex five days before ovulation, it’s a 10% chance of pregnancy, and sex on the day (or two days before) ovulation, is about a 30% chance.

American Pregnancy Association also says that 30% of couples get pregnant within the first cycle (usually about a month).

So, that could be from having sex just one time at the height of your ovulation, or from several times during the ovulation period.

But, of course, your chances depend on many other factors, too, including your age.

For example, the chances of becoming pregnant are much higher for women who are under the age of 35.

That’s not to say you wouldn’t become pregnant after 35 though — just, that your chances of conception will likely change.

Can I get pregnant if he only went in once?

Yep, you certainly can.

Whether he went in once, or multiple times, if any semen could have been on his penis, and then his penis entered your vagina, you run the risk of pregnancy.

It doesn’t matter how much of the penis went in, either. 🍆

Whether it was just the tip, or the whole shebang, if any sperm gets into contact with your vagina at the right time in your cycle, pregnancy could be on the cards.

What should I do if I had unprotected sex, but don’t want to become pregnant?

We get it, sometimes, the heat of the moment just takes over. 🌶️

But, it may result in circumstances you’re not quite ready for, or may never be.

In these cases, you can take emergency contraception (known as the morning-after pill) to prevent pregnancy after sex.

These pills, like Plan B, can prevent or delay ovulation, meaning that if you’ve had sex before you’ve ovulated, this could stop you from becoming pregnant.

It’s typically 95% effective when it’s taken within 24 hours of sex, and 61% effective when taken between 48 - 72 hours after sex.

But, if you’ve already ovulated, or think you’re currently ovulating when you’ve had sex, you may consider having the emergency copper coil fitted, instead.

This IUD works to stop the egg implanting in your womb, or being fertilized after you’ve had sex.

Plus, it can offer you protection against pregnancy for up to 5-10 years…

So if you’re trying to avoid having a baby, this could be a good method of birth control to try.

If you are trying for a baby, chances are you’ll probably have to have sex more than just once to conceive.

Tests

So I had a blood test at the drs bc I keep getting positive tests when the blood test was negative what could this mean? Hubby says the tests are negative and said he can’t see anything. Negative image down below.

Am I pregnant?

I lightly spotted almost 5 days ago, which is not common for me before my period.
My period was supposed to come today. I should have tested in the morning but its 5:30pm.
Is there a second line??

Anyone have this happen before?

We were not trying to conceive, used protection and had sex on week 2 of my cycle (accidentally on my peak ovulation day). Week 3 we had Flu A. Week 4 my period did not come (it’s very regular). I tested and it was negative (2 different brands).
What should have been week 2 of my next cycle (now 6 weeks post last period), I had light red/ pink spotting for one day when I wiped. The following week, I tested again, still negative, but this time almost all the dye was in the negative space, which I’ve never seen happen before. The area where it shows one horizontal line for negative and a plus sign for positive, the horizontal line was super faded at the 3 minute mark, and the negative vertical line in the next window was VERY dark. Now I’m on week 8 of all this, period did not show up yesterday. Nothing in my life has changed (no additional stress, no other illness, no changes in diet or exercise, etc).

Has anyone gone through this and NOT been pregnant? I’m super nervous as we thought we were done having kids.

PS. I know I should go get a blood test, does anyone know if urgent care will do that? I’m past being convinced by a pee test.

Help pls

I'm 7 weeks pp. Not had sex or even done anything but my tests have come back positive. I wouldnt test but had symptoms of pregnancy so I tested. What does this mean? Google says it should have been negative at this stage unless its a new pregnancy or bits of placenta has been left behind. I had a c section so 🤷‍♀️

Is it normal to test positive still? (Wouldn't usually do one)

Not the best pic and clearer in person. Is this normal? I've not had any sex since having my LO but I've had strong cravings, sense of smell is strong and my hair still hasnt started to fall out. Im 7 weeks pp so 🤷‍♀️ I wouldnt normally bother testing but with those symptoms that I never really have its like whats going on. Cravings for something very specific too and can only get from KFC now 😩 so its annoying

Can baby mamas be friends?

My son has an older brother from his biodad. Biodad has never had contact with my son. One thing lead to another though and the other child's mother and I got in contact and are planning a meeting for the boys. Biodad has no idea any of this has happened. Biodad also hasnt had contact with the other child in about 2 years. Just thoughts, opinions, anyone been through something similar?
Edit-Thank you all! Have definitely been feeling somewhat weird about it because we never met before but now know it can be a good thing definitely helps. I can't wait for them to meet. My son has been asking for a brother and I can now happily tell him he has one. That just happens to be 13. Im sorry for yall that fight/have issues with the other baby mamas. Sadly some women rather be stuck on the men, when the kid is the one who really matters. They're the ones that end up getting hurt and missing out.
