I rubbed penis over my gf vagina for a second naked. Then I wore my underwear and through underwear I rubbed her vagina for seconds and I little ejaculated in my underwear and the wet section slightly touched her vagina. We did this on 2nd of Sept. She had her prd previously on 5th of August last for 6 7 days. In the month of Sept she did not get prd as if of now. Does rubbing penis like this leads to pregnancy ? Plz answer doc. I'm very much stressed
