So I was due for my period on the 20 and I got what I thought was my period on the 19. It lasted two days and then stopped completely later the second night and then the next two days it stopped. On the first day I had an awful pain in my bladder that shifted to my left side bladder area and it hurt every time I got done urinating. I have been feeling like I'm on my period but haven't been on it. It said my ovulation cycle started yesterday and I took at test at 5:45 this morning and the dark dark lines read negative but when I got up at 10:00 this morning I looked again and I have a very faint almost invisible positive line. Suggestions?
