Could I be pregnant?
I am 17 years old. I am married. My period is 18 days late. I have taken 2 pregnancy tests & they were both negative. Recently I have noticed a change in my breasts. They have gotten larger & my nipples have got darker. I also have felt a very fast heart beat in my lower stomach close to my left ovary. Other people have also felt it & I was wondering if it is a sign I am pregnant? It's a different pulse rate than my own. They have placed their hand on my wrist & my ovary & the rates are completely different.
