I took plan b around 3/27. I got my period about a week or so later in the early part of April. I havent had a period since then and its June. ive felt a few light menstrual cramps recently but nothing and today I feel normal. Ive taken to pregnancy tests and they are both negative so i am sure I cannot be pregnant. How long does it take for my cycle to get backto normal? What is the best way to address this?
