Advice Needed, Please help!

Dear Nurses,

I know I have posted elsewhere on this site but I really need help and soon.

I was put on birth control about 2 1/2 months ago. Should I still be feeling any side effects? I am having headaches, sometimes my stomach really hurts down in the abdomen area. I feel like this pounding in my lower stomach (almost like a heartbeat). Could I be pregnant? I had sex like three weeks after being on the pill. I did take a home pregnancy test twice, once in the morning and a week later at night, both of them came up negative. Could it be just my nerves considering that I am planning a wedding for July of 2005? I am scared. I did have my last period about 2 1/2 weeks ago but it was like for two to three days long. Let me know as soon as possible.

Thank you. If you need any other information I will be happy to give it to you.
