So me and my boyfriend had sex on monday april 8. The condom broke and he went fully inside. We got plan b one step 20 min after. Ive been feeling really nauseous and just kinda sickly. I ended my period on april 1 and typically have a 32-34 day cycle. I read that plan B doesn't work if ovulating. Im not sure if I was or not. What are the chances or me getting pregnant? Im really worried if Im going to end up pregnant or not....
