Like mentioned before it can be very easy depending on factors but some times it takes a lot more work than that like how long you’ve been off birth control etc
To put it statistically women only have a 20% -40% chance each month to become pregnant so chances aren’t wonderful as they are normally lol
There are so many variables to getting pregnant. No one can really answer that. There's up to a 42% chance of getting pregnant during your fertile window, according to Google, but it also takes perfectly healthy couples upto 12 months to concieve.
