Me and my boyfriend had sex on the 9th. He put the condom on inside out , then corrected it once he realized he couldn't roll it down. I didn't pay attention to if he pre cam or not. There weren't any leaks in the condom, but could I be pregnant? My period is 2 days late, but my period is usually almost a week later than what my app tells me anyways. I'm extremely worried. My closest friends have told me I probably have nothing to worry about, but I can't help but to worry.
