### output:

Hi, I think periods can get delayed due to stress factor also. Wait for one more week and do a urine pregnancy test at home if you don't get periods by then. If test is negative, you can take some medicines like me prate or devilry for inducing periods.  If you are breastfeeding your baby there is a chance that you are not ovulating every month and that may be the reason of delayed periods.  So, you can track your ovulation by repeated ultrasound or by ovulation detection kits. Be in contact with your husband every 2 to 3 days after your periods stop. It will increase chance of pregnancy.  Hope it helps.
