Hello, I last had my period around March 6 and ended about the 11th. I had unprotected sex on March 17 but the guy didn't cum in me or at all because we ended up falling asleep. I've had no pregnancy symptoms until 3 days ago my nipples started feeling sore and I feel bloated with cramps and i'm breaking out. But i'm not experiencing nauseous or headaches and i have been active so no tiredness. I took 2 Clear Blue tests and both were negative. On April 22 I took the Clearblue digital in the afternoon and it came up as Not Pregnant and the next morning I used my first urine to test again and I got a bold negative. But i'm still worried because I have been cramping and my nipples hurt. I'm 3 weeks late so my question is, is there a possibility for me to get a false negative using Clearblue, I drink a lot of water so could it have diluted the hcG and give me a false negative? How accurate is ClearBlue? If i were I was to be pregnant i'd be 7 weeks and I've pressed in my abdomen and I don't feel a womb growing or a baby bump. So am i just freaking out please help me.
