I believe that I am pregnant and I am almost 20 days late. I took a clear blue test about an hour ago and the result is not pregnant. I've taken 3 other tests one on the 7th one on the 11th and one on the 20th all negative. (first resopnse test) I plan to take the next test on the 7th of next month. Could something be wrong since I'm getting negitives? I'm kind of worried. Is this normal considering if I am I would be 7 weeks tomarrow??
