Hi, I had sex with my girlfriend for the first time on Sunday, March 19th, 2017. I have ejaculated 2 times on 2 occasions but on the same day. Her previous period started on March 8th. I have used a condom for both but I did not know that I was supposed to leave a space for the reservoir at the tip. Although when I put it on I pinched the tip, but during intercourse I did try to get rid of the space at the tip by adjusting the condom (pulling it back). I came inside her and the condom seemed fine(though I regret not pulling out), but when I took off the condom I saw white fluid INSIDE the condom and it felt wet on the shaft of my penis. I'm very scared because it is also on her fertility period and I didn't know. Although we used a condom for both occasions, I'm not sure whether to get emergency contraception or not(its almost been 72 hours). I'm also very worried and concerned about what would happen to her health after taking it because I don't want to ruin her fertility with the side effects but I also don't want her to get pregnant. Thank you.
