I had sex with the guy I'm dating last night and it was protected and all. The first time he came in the condom and we tried to have sex again but there was nothing left in him. So after the second time I went down on him and then after he fingered me & went down on me. He told me today he thinks he had a small bit of cum on his fingers and wants to buy me plan b just in case, but I feel like it would've wiped off given that he didn't finger me right away. I'm not ovulating or fertile rn, and I have a huge exam tomorrow I'm studying for so that's why I'm not freaking out like I probably would. I've never taken plan b before though. What should I do? I want to be cautious but I'm nervous to take plan b. My period is due this weekend anyway. Ladies, please help!
