My fiance has been having several things wrong with her, and I really don't know what it could be. First, I need to inform you that she is on birth control pills, and has never missed a pill or taken one late and is now on her last week of the fourth month. We haven't had sex for quiet a while, but when we do we always use a condom. Now onto the symptoms that she is having. They include: random headaches, slight spotting in the middle of cycle, stomache aches that are sporadic and come and go, and mild back pain. It is also important to tell you that I had her take 3 different pregnancy tests, and they all came out negative. These test where taken 1 and a half months ago, and the other two were taken 2 weeks ago. We are very stressed out because of this, and she is fearing all sorts of different things. If someone can please help, that would be fantastic.
