Hi doctor, I was on micronor (norethindrone) For two years. I stop taking them 15 days ago because im planing to have My last baby. But My period hasnot start. I ha?

Don't fret. Resumption of menses/withdrawal bleeding after being on OCPs (oral contraceptive pills), especially progesterone based ones like the mini-pill can be erratic. Remember that this particular OCP works primarily by suppressing ovulation like most OCPs, but, at the local level, thins out the uterine lining. This means it may take a while to get it built up again and get your uterus back on track.
