My last menses date was 20 Feb.I started taking contraceptive pill SAHELI on the same day.I took all the pills on time and stopped taking on 13 march. Now I havenot got my menses.Could I be pregnant? I am diabetic and also has thyroid problem.

Saheli is a weekly birth control pill, Why did you stop taking them? If you just started these pills after never having been on them before, your period may be irregular while your body adjusts. If you have been on them for a while, then take a pregnancy test, or better yet, discuss with your doctor.
