Ok last night my boyfriend and I had sex but I know I was ovulating because I follow my cycle on an app. But he never came in me he did put it in for a little bit before we put the condom on, I know that's stupid. But he came in the condom, but I'm super nervous because I was ovulating last night so for the small amount of time he was in their without a condom I feel like I could get pregnant even tho he didn't come. So if I take a plan B pill today will it still work even though I was ovulating last night? It's only been about 8 hours. Please help I'm freaking out.
