i am 25 years old. I got my last periods on 18 th january. On 26 th afternoon, 27th night and 29 th morning me and my fiancee had sex. He just rubbed his penis to my vagina. He didnt inserted it not ejaculated. I am worried because its my ovulation period. on 29 afternoon within 4 hours of last sex activity. Is there any thing to worry? i have taken ipill.. so is there any problem?
