I am 19 and I have been pregnant before but it was when I was 14. I think I am pregnant but I am not really sure. I sometimes feel nauseated, I have alot of extra discharge, My senses have become very strong, and I also have started to become very hot. I was on depo until dec 26. Then I started taking yaz birth control pills but I only took about 10 because they started to make me sick. So I have been having unprotected sex, but I am not sure if I am pregnant.
