My husband and I have been TTC for about 2 months now, I'm having a full bloating kind of feeling, my stomach feels really tight like its stretching; it's very uncomfortable. I've been urinating more often and having lower abdominal and lower back aching. I started what I thought was my period on 9/23 which was almost 2 weeks late and I'm supposed to be on my last day but still have some fresh bright red bleeding, and it's a bloody mucus kind of mixture. I've taken two pregnancy tests in the last month and a half and they were negative. Could I still be pregnant?
