How long will it take to get my period? (please help)

Jen
I stopped taking the birth control pill that I was on and finished my last pack around the beginning of February of this year. For anyone who has stopped the pill, how long did it take you to get your period? I haven't gotten my period since that week (it's been about a month and a week) and I don't know if I should be worried. A few days after I got my period my boyfriend and I had regular sex with a condom and then we switched to unprotected anal sex and he finished inside me. I was pretty sure none got near my vagina, especially since I showered right after and cleaned myself off but now I'm not so sure. Also my periods were not very regular before I was on birth control and the reason I stopped was because I was pretty sure they were too high in estrogen for my body. What are some of your thoughts? Could I be pregnant? Am I freaking out too early? Another thing to mention is my breasts have been tender for the past three days and I recently got a yeast infection
