Dont worry

Detailed Answer:
Hi,
Thanks for writing..
I understand your concern..

I would like to know your last menstrual period.. Plan B contains high dose of hormones which is the cause for the irregular period.. It also causes irregular and heavy periods which will last only for a month..

Did the second episode of bleeding come on the date when periods was expected? It the bleeding is heavy, take tranexemic acid for 2 days. This will reduce the bleeding.. Drink lots of water and fruit juices to avoid dehydration. Take iron supplements to restore the lost iron and improve the hemoglobin level..

If the bleeding doesnot stop after taking tranexemic acid, a scan need to be done to detect any other problems.

Hope I have answered your query.. Feel free to ask any doubts.. Good day..
