My boyfriend and I have sex yesterday. When he pulled out his penis he is ejaculating. But he said that he just ejaculated after he pulled out and not on my vagina. Then second we used condom. After we did sex we noticed white fluid on the sides of his condom. I don't know if it is semen or not. I don't know if i have irregular period but last november and december i think it became regular. I don't know if I am done ovulating or not. Am i at risk of pregnancy?
