And while we're on our honeymoon....I was on birth control the pill and stopped it in period is finally on a 28 day cycle..and last for 7 it's back to normal thank god lol...I know I need to lose weight before I get pregnant because I'm not the weight I wanna be for our wedding...I was just wondering what else I can do to prepare my body for pregnancy
