My boyfriend finished in me last week 4 times. It was the first time he did and one of the days I was fertile. I was cramping a couple days after and I was nauseas. I was going to wait to see if I had a missed period to take a test. Today I was using the bathroom and I cleaned my self and there was blood. My period isn't supposed to come until 5 days. What are your opinions or has it happened to anyone else?
