I just went to the bathroom and found some old (brown) blood in my underwear. My doctor isn't in today, so I can't really call anybody. It's just brown, not red, and I didn't even really see much on the TP when I wiped, but I'm scared. I haven't done anything that I can think of that might have irritated my cervix, no DTD, no exercise, no heavy lifting, nothing. I'm not really crampy, maybe just a little dull ache in my pelvic region. Should I be worried? or is this kind of thing pretty normal?
