Hi. I have been on birth control for 3 years and in a monogamous relationship for also 3 years. We recently went on vacation and had an accident (he finished in me) on November 15th. I had started a new pack 3 days before that. I also took plan B on November 17th to be safe (even though I know I am safe with birth control because I never miss a pill). It’s been a week since I took the plan B and I am supposed to get my period a week from today according to my pack and when the sugar pills start. Right now I am having cramps but I usually do get cramps before my period comes. I did not have any other side effects from the plan B and just want to do if this is an idication I’m pregnant or just that my hormones are messed up because of the birth control and plan B mixed together.
