Hello Doctor,
I was wondering if you can help me better understand the risks and variables associated with a pregnancy scare my girlfriend and I are currently having. To summarize: we had unprotected sex a week ago on July 17. We used the withdraw/coitus interrupts method. Within an hour of intercourse, she also took Plan B One Step. There were no other instances of unprotected sex this month. Our concerns are two-fold: Firstly, we read that there are recent studies challenging the efficacy of Plan-B one-step after ovulation. In our case, it is difficult to guess when ovulation occurred (if at all) because she suffers from PCOS. In fact, this condition has caused her to miss her menstrual period for the past two months. Also, I saw in related literature that new research calls into question the efficacy of Plan-B in overweight women, which she is. In trying to ***** our risk for unwanted pregnancy, things are further clouded for me by the fact that when I recently had a sperm analysis done, the results showed low motility and low-volume due to a condition that my doctor calls "retrograde ejaculation". We are anxious because this would be a very difficult time for us to have a child. Could you help us gauge our risk for unintended pregnancy in this instance? Thank you
