Monday night my boyfriend, of 3 years, and I had sex. We wore a condom and I am religiously taking my birth control. Unfortunately I started taking my sugar pills Sunday. After we had sex on Monday, he realized our condom broke and he had came inside me(which has surprisingly never happened to me before) so I panicked and the next morning (10 am Tuesday) we went and got a plan b pill just to be safe. My period was supposed to start today (Wednesday) but I've only noticed slight spotting. The plan b pill has also intensified my cramps, to where they are worse than before I got on the pill. 


Basically I just need some reassurance. Did I do the right thing? Should my period come? Should I continue my birth control regularly, come this Sunday? 


Thank you in advance.
