Hello and welcome, I understand your query. It would help to know your age as the treatment varies with age. The first thing is if you had a thick endometrium, an endometrial biopsy is needed. From the biopsy we can determine the nature of pathology and then treat it accordingly. Taking femilon without a biopsy is not advisable as the pathology may not be responsive or sometimes even aggravated by femilon according to the condition. So please discuss this with your doctor. Regarding the lower abdominal pain, it may be due to infection or sometimes even utero vaginal prolapse. So get this also evaluated. The lethargy may be due to hormonal imbalances. Please get a serum TSH done for thyroid abnormalities as the commonly cause this. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have.
