### input:
My name is Elli and i am 16 years old, i have been ill with something that the gyneacologyst in my town cannot recognise. My illness includes excrutiating pain in the lower-abdominal area, and i also have servere depression. I have been taking Yasmin, a contraceptive drug to ease the pain of my periods, I used this for 3 months with a 5-day gap, as you would normally take it. For the past 3 months, i have used this as she ordered me to, to take it once a day with no gap in the month. So, I have not been having a period at all for 3 months, and now through the past week, i have had a dark-brown substance which has no smell, i am guessing that it is blood, although when i used to have periods, they were very heavy, and this is not.I do not know why this is happening to me, please can you provide me with an answer or advice please? P.S. i am also taking several prescribed pain-killer drugs to ease my pain, ibuprofen, codiene phosphate, St. Johns Wurt (for my depression), and audmonal.

### output:

Hi Ellis... Thanks for your query and specific information and understanding... Pain in lower abdomen and severe depression and inability of the gynecologist to understand your problem can be due to :-Yasmin has altered your hormonal environment; so no periods for 3 months; I would advise you the following:Ultrasonography of the abdomen and the pelvis to see for PCs and / or any other problem. Hormonal assay of the blood. Second opinion of the General Surgeon to rule out any other possibility like appendicitis, colitis or so. Proper diagnosis will lead to a proper treatment to take the least possible medicines as there is likelihood of addiction to the medicines you mentioned like Ibuprofen, Codeine, St Johns Hurt.
