[Worried09]

I had unprotected sex in August and I have been having symptoms since then but I have been having my normal periods, I did have nausea, dizziness and sore breasts, recently I have also gained weight and my stomach has started to stick out and get harder. I have done 2 pregnancy tests but they both came bak negative so I have been trying to convince myself I am not pregnant but I am really not sure as I have been suffering from back ache as well as my breasts have grown quite a bit, because I am underage I can't talk to family and I don't know where I could go to find out whether I am or not.
