So my ex and me had sex and when he came we realized the condom had broke. Within 30 minutes we had already went to CVS to buy the plan b pill. The problem is I am in my ovulation window so I don’t know if it’s going to work. My sons father decided he wanted to try and fix things after 9 months and we plan on being together again and we move back in with each other on the 20th of this month and I know he’s going to want to sleep with me again. He knows I was seeing someone else and isn’t bothered by that but I don’t know how to tell him that I had to take a plan b so I would prefer not to have sex anytime soon! If I wait at least till the 20th or 21st and we end up having sex can it possible still be the other mans baby?
