We went in raw!!

Yesterday I went to vist my boyfriend after my class because he had invited over at 2 p.m.Turns out he was preparing lunch for me but I declined the offer since I had already eaten earlier.I noticed he was upset but didn't show it.Moving on he suggested we make out which we did.We did foreplay for a while and we returned to kissing each other and that's when he told me if he could insert it but won't nut.Okay here comes the terrifying part so I've been on Microgynon 30 for the past 2 wks and 2 days but I honestly have trust issues and I'm afraid I may get pregnant . I've been taking the pills on time, I haven't diarrhed or vomitted within 3 hrs after taking the pill but every single hour my mind would remind me he went in raw and I could be pregnant.Anyone who's been on Microgynon 30 to tell me if it worked for them or not
