I was wondering if anyone can help.. I am 20 and me and my parter had unprotected sex about 7,8 weeks ago. Lately I have been experiencing tierdness, headaches, cravings, nausea and have been needing to urinate more than usual, I have also been having pain in my lower back and abdomen. I have been taking home pregnancy tests but they keep coming back negative. I still have my normal periods but they have been finishing earlier than usual. I asked around and few people said that they had still been on their periods throughout their pregnancy and that their tests came back negative. They said I should go to docters to jsut make sure. I'm worried that if I go I might be wasting the docters time. Im not sure what to do. My innstinct is saying I am pregnant but not sure what to think.
