Long story short, my ex-girlfriend and I had sex. I wore a condom and pulled out before coming. I thought it was pretty safe. However she told me that a few days ago her breasts became more sensitive to touch and her sense of smell became sort of acute. Both symptoms only lasted the one day.
My friend told me that often women who are nervous or stressed about a pregnancy can cause themselves to exhibit these symptoms. Is it true? How worried should I be? I checked the condom after sex for breaks, there were none, and I barely came that time. So i'm confused as to how we might have concieved (although I know the failure statistics for condoms and all of that.)
the question -- knowing that this girl is one to stress, how likely is it that these symptoms are real, given that they occurred for only one day about three days after we had sex?
