My last period started around December 28; as with my other periods, it started with faint brown discharge, then about two days later, switched to "regular" period stuff. I'm pretty sure I ovulated when I was supposed to (January 13 or 14), judging by the discharge that I had, but I did notice that this time, the discharge was bloody--not something that I tend to experience. In fact, I think it's the first time I've ever had bloody ovulation fluid. A week later, around January 20 or 21, I had unprotected sex.
For the past few days or so, I've been experiencing some cramps, but no discharge whatsoever. The fact that I'm usually like clockwork (28 day cycle, with only a one- or two-day variation) makes me a little bit nervous; I got pregnant a few months ago while on a copper IUD, and I'd really hate for that to happen again.
Should I be worried? Thanks in advance.
Edit: I began my period last night, so I guess I worried over nothing. Thanks for your reply, frolicnaked!
