On June 20th I went off of birth control because I m trying to get pregnant. I had only been taking birth control for about 3 months. During the first 3 weeks I was off birth control my husband was away because he is in the military and had to go to a training at another base. On July 8th we had sex, and then the next day I got my period. 5 days later (July 13th) we had sex again even though I still had a light period. After we had sex that day my period completely stopped, and 3 or 4 days later I started to get cramping on one side of my lower abdomen. A few days after that I started to feel bloated and cramping throughout my whole lower abdomen. Now this past week I still feel some cramping and bloated, but my breasts are also a little swollen and tender and my nipples are constantly erect. In the afternoons I have been getting severe headaches and fatigue, and during the day I feel very dizzy and lightheaded. All around I feel different than I have ever felt before. I took a home pregnancy test this morning but the result was negative. Is this possibly a false negative because it s too early? I have an appointment with my gynecologist next Thursday because I told her I m trying to conceive and may already be pregnant. I was hoping to have a positive home pregnancy test before my appointment so my doctor can do a blood test. Is it still possible that I am pregnant?
