I had sex with my girlfriend last week when i was putting the condom over my penis i putted it then I realized that I'm wearing it from opposite side as it is meant to be wear and i had a pre cum over my penis so i switched the condom on different side. And then i wear it and we had sex so can she get pregnant by this? She's had delayed her periods her date was to be on 12th November and it's 17th but still her periods doesn't happened and today she's having stomach ache when she's bending and laughing So is she pregnant or is it from something else? After sex i checked the condom it wasn't leaked and it doesn't had any hole in it.
