Anyone have any experience in this arena? I had two peaks this cycle. The deed was done during both, though the second was 2 days before my period. Since my period started, nothing came of my first peak obviously since I started bleeding/period. But if sex was had on the two days leading up to it (after the second surge) could I still concieve during a period? Would the period, for lack of better words, "cancel" the whole process?? Any personal experience here or knowledge for me?
