This might be an odd question, but I'm going to shoot anyway. Before I was married and had first time sex, I had a really regular menstrual cyle. I could time things fairly exactly without any variations beyond 2-3 days. After I became sexually active (pretty much right away) my cyle got way out of wack. Everything is normal except for the timing....sometimes it's three weeks, sometimes four, sometimes 2 1/2....the point being, I'm having a hard time finding a pattern, which is weird because I've always been really regular.
I've never been on birth control (we use condoms) and am not on any medication or health variation. Has anyone else experienced this kind of fluctuation after becoming sexually active? (I hope this isn't a stupid question...)
