Had not intercourse but his penis was inside vagina for not more than a minute, and when he removed he saw a drop of precum over his penis, I washed my vagina and in 20 hours I took ipill too. I also experienced radish pale urine 2-3 times, and a little blood piece once in the urine. My periods were about to come on 27 july but have not come yet. I am worried if I am pregnant.
