It's not likely, but it's not unheard of to ovulate late.. with my youngest I had ovulated 9 days late!
Cycles are often irregular for awhile after you have a baby. It could be that you ovulated late and then ended up having sex during your fertile window and now you're pregnant, or it could just be that you ovulated late so your period isn't actually due yet. I would take a pregnancy test, but if it has actually only been 5 days since you ovulated, it's still too early for it to be accurate.
It’s not a precise science unfortunately. You can ovulate anytime in a month. They’re saying that abortion rates are up as people are just relying on dates on apps instead of taking temperature, mucus and until they know their body ovulation test. Of course sprm lives for five days so any action on the days leading up can also cause a pregnancy even after that
Anytime you have unprotected sex, you could get pregnant because you never know if you ovulate late or close to that date since the sperm can survive a few days. Might as well test so you know and can make whatever decisions you need to.
Sadly the only way to find out is a pregnancy test xx
