Hello doctor, I had sex for the first time Saturday night & it is now Monday night. I m feeling a weird ache in where I d believe is the inside of my vagina, because it s fairly low in my pelvic region. The ache is not exactly in my lower left & right sides of my abdomen area, which is where I d normally experience menstrual cramps, it s slightly lower than that & in the middle (if that makes sense). We did use a condom, 2 actually, we used a new one after the first one sort of slid off. But I was wondering if there is a possible chance of fertilization occurring after the slip-up , & if the ache is hopefully not like possible implantation going on, but more so that it is just because it was my first time so the inside of my vagina is just sore. It s not an unbearable pain, it s more of a weird aching feeling that I ve never really felt before, so I m just asking because I usually like to know & have some sort of control over what s going on with my body. -Thank you for your time.
