I had pull out sex during ovulation two weeks ago. And now i notice my nipples are sticking out. I have the usual mild cramps and sore nipples i usually get before my period. But i feel like ive been peeing more and my nipples are protruding but im not sure if its just in my head, and that my nipples always stick out before my period. I cant remember my nipples sticking out so much before my period. I know pull out method isnt 100% effective but i use it for 4 years no issue. The reason that im a little more paranoid that i may be pregnant because that was probably the first time i had sex during ovulation.

How likely is it that i may be pregnant?
