My period ended a week ago, Me and my boyfriend had sex with a condom on Friday night/Saturday morning but it came off and he finished inside me. I have been using the birth control patch for about a year now. My patch change days are Saturdays and on Wednesday I had to put a replacement patch on bc the other one was partly coming off and I continued my normal change day this previous Saturday. I also used the one step plan b pill 15-20 minutes after sex. I was wondering if there is a high chance to me being pregnant or if I can calm down about it. My period should be in two weeks but I'm so worried and it's only been a day or two, I will give any information to find out if i should be worried if I'm pregnant.
