About two weeks ago me and my boyfriend were playing around. I was on my third day of my period and we decided not to have any sex. But still did doo some stuff. He finished on my buttcheek. And had his fingers inside me. He whipped off all the sperm. When I got home about 2 hours later I showers ..and kept a regular cycle. It's been 15 days and I don't have any pregnancy sings should I be worried ?
