I had sex Saturday night/Sunday morning it was protected (condom) as far as I can remember we did have bare contact for a few seconds before he put protection on as he thought I was on some myself. Two days later I am having slight back pain and cramps in my left and right side, nearly feels like periods pains but I’m not due for another two weeks and don’t ovulate until the 28th, he said I’m just being paranoid as he didn’t come. Any help would be much appreciated.
