Hello,

Welcome to the forum. You have written nothing about your past symptoms/ menstrual history or illness. However I will try to help you. You are suffering from the side effects of Regestrone. Take balanced home made food rich in iron, calcium/minerals, oxidants, fiber. Regular exercise and adequate sleep will help you recover well.

You can take some energy drinks or vitamin supplements for a week or 10 days to feel better.

Regestrone is a Norethisterone. It produces side effects like nausea, vomiting, breathlessness, mood changes, loss of libido, etc. You can take any other substitute for it that suits you better ( if you are taking it for your menstrual disorders ).

If you are using it for contraception, you can stop taking it and use barrier method for contraception like condoms, other hormonal pills, Cu-T or permanent sterilization. Take care.
