K.P.
Well after I had my son I got on birth control. I had my period every month, but then after 4 months i stopped taking the birthcontrol because it was making me moody and i never remembered to take it. When i stopped taking it i didnt have a period for 3 months. Then it started back and ive had a period every month since then. I weaned at 13 months. So I only went 3 months without a period. I think it depends on the person really.
