###Human: Kindly explain the reasons for missed period. ###Assistant: Hello. Do not worry about the periods, as you are aware that delay in periods can be due to obesity as you had suffered last time, however my compliments to you for reducing 14 kg of weight (attachment removed to protect patient identity), so we can conclude that delay is not due to being overweight. Then delay can be due to hormonal changes due to various medications specially birth control pills, etc., which you are not taking. Stress is also one of the major reasons these days due to Corona and associated problems. Pregnancy can be a reason but only if one is sexually active, and you are out of that risk as well. May be the cramps you had are signs of periods onset, we can wait for 2-3 days and may be then start with medication.
