Re: Could I be pregnant
If you won't go to the doctor, all you can do is wait and see if you miss your next period. If you do miss it, get a pregnancy test from the drugstore and then you will know.
I don't think it's wise to assume pregnancy based on symptoms. First of all, it takes some time for women to start having pregnancy symptoms - more than just a week or 2, and second of all, the symptoms are so similar to PMS that there's no way to know if it's just your period coming or actual pregnancy. I think you're way better off waiting to see whether you get your period or not and getting a pregnancy test if you miss it.
