Not sure who the father is...? I had 2 periods in January and didn't have a period in February. I had sex with my boyfriend the 1st, 7th, 9th and 10th. But had sex with my ex the 9th BUT he wore a condom after he took it off and used the bathroom then we didn't have sex for another 15 minutes without but it didn't last long not even a minute because once we got started he kept stopping cause he said he didn't want to cum in me which is fine but still. I doubt it's his because he takes creatine and he drinks a lot she had smoked cigarettes and marijuana since as long as I have known him. It has me nervous. Help me please!
