I had sex with my gf....on 24th of june...we didn't do any penetrative sex...i just rubbed my penis into her vagina by wearing two condoms...and i also had pre ejaculate and i spread that over my penis and i fear that that ejaculate spreaded on my hand and i fingered in her vagina..she had her last period started on 1st june and she said she have 30 day period cycle..and after all these..she had spotting on june 27th and now it's 4th of july and she didn't have her period yet...is there any chance for pregnancy?
