I had sex with cloths on on 4th march. While having sex with cloths on I (boy) cummed in my underwear and the my jeans got damp which also touch her underwear above her vagina. After that she is having all 7 periods till now. Serial order is 6th march, 12 april 12 may 14 June 19 July 18 august and 19 September. She once vomited in may. And became ill during march to april. Can she still become pregnant from the sex with cloths on done in march 4? Can breakthrough bleeding happens every month like periods?
