I got my period in March, then had unprotected sex with my boyfriend that same month and took a plan b and because of that I guess I got my period for the second time in a month. Then I didn't get my period in April then got it in May and also in June but with really messed up cycles. I didn't get my period in July and now is August 9 and still nothing.

(That was the first time I have ever taken a plan b and I have never been on birth control pills.)
