It's very normal for women to just have off cycles in their lifetimes. It happens for dozens of reasons, and sometimes for no reason at all. You definitely need to take a pregnancy test if the bleeding you're having is not normal for you. If it's not, more than likely it's not a true period and pregnancy could be a very real possibility. Are you trying to conceive?
No we are not. I am still having a dark brown but sometimes more blood for no more than an hour most of the time it looks like its drying up but then doesn't so I don't think I am pregnant. I stop at night then start in the morning and it has been 8 days now. Going to see the Doctor Friday.
