I had unprotected sex on the 30th of March, it is the 20th of April. I am not experiencing morning sickness or dizziness/ fainting, but I have lower back pain occasionally and am tired. That being said I am a teenager  who plays lacrosse, I work out often and go to sleep at later times.. so these symptoms seem normal to me. I haven't missed my period yet, and the only weepiness or mood swings I experience is me freaking out about maybe being pregnant. Overall I feel healthy and not bloated, constipation happens sometimes but that isn't irregular for me, implantation bleeding also did not happen. I'm aware that the pull-out method is only 70% effective, I just need someone to talk to. I know everyone has pains & twinges in their bellies sometimes but I just need some advice or guidance or something to help me out.

Thanks
