Im 19 years old and been with my boyfriend for 3 years now. I just recently finished cancer treatment for leukemia, while i was going threw treatment i was unable to get pregnant due to the fact i was on so much medication. My boyfriend and i did not use protection threw out my treatment only cause i couldnt get pregnant, but now that im done with treatment him and i continued to have unprotected sex thinking i wouldn't get pregnant. But now ive missed my period the whole month of September. Ive been throwing up and having nightmares. Im not sure if im pregnant and i dont know what to do to set up an appointment to be checked by a doctor. This is all new to me. Help?
