My gf came to visit me for a week and during the beginning of the week she was ending for maybe the first couple days her period cycle.We had sex everyday unprotected, we love eachother and if a baby does happen well be ready and happy, question is its only been maybe 2 weeks and she is feeling slight pinch pains in her left ovary.nothing severe.could this be due to implantation and maybe very early sign of pregnancy or another problem?tips and advice would be much appreciated ty
