I am 24 days late for my period. When I was supposed to get my period I had some mild cramping but no bleeding. I took two home pregnancy tests one had a faint positive the other was negitive. I went to the doctor and had a blood pregnancy test done and it was negitive. This was when I was a week late. A few days later my breasts got tinder and my nipples sore, I am very sleepy alot, also sick to my stomach, and mood swings have been occuring crying at stupid things that normally wouldn't bother me. So my question is is it possible that I could be pregnant even though I had a negitive blood test? I get the distinct feeling that I am pregnant. I felt like this when I was pregnant with my daughter. What could be going on? Thankyou.
