My period this month has been very irregular for me. Usually I have heavy periods in which leaves me in so much pain that I don't even want to get out of bed. But this month my period started and was heavy the first day. After that day though, my period was stopping and going. It's not old blood, it was fresh blood and more of spotting. I wore a pad all Saturday and there was nothing. But the next day I started having a brown watery discharge, but not enough to have to wear anything. I have only had this happen to me once before and it was right before I found out I was pregnant. I have a 7 month old now. When I was pregnant with him before I missed my period, I had a period like this. I didn't take a test though. Not until I missed the next one. I had unprotected sex all of last month and even had sex on an ovulation date. I seem to have some symptoms. I have severe diarrhea to where it just comes and I have to go right then. I also feel nauseous for no reason. I know that I am not sick and have taken my temperature. I took 3 pregnancy tests and they all say negative. Could it be to early to tell or could it be something else? My period last month was very normal. Thank you for the help.
