Hi, I 22 years old, been on birth control for 6 month, and then went off birth control for a month and half already. My period has not came back yet!! I have no medical problems in the past or in the present. When will my period come back?? I am scared that I won't ovulate again. (also, I am 100% I'm not pregnant since I've been abstaining after I've been off birth control, and also my pregnancy test came out negative). Please help. Am I ever going to ovulate again?
