So, about 10 days ago I posted about having a brown discharge, but not having a actual period. Well, I still haven't had a period. Mine are usually on time. I've never had one late like this. Sometimes they'd be late due to stress of husband gone for work often. I was dealing with some stress earlier this month, but now everything is back to normal. I have taken 3 pregnancy test and they are all negative. I have no period symptoms and no pregnancy symptoms. Any ideas?
