Drovelis pill and pelvic infection

Drovelis was prescribed to me as a third combined pill to treat adenomyosis (endometriosis) and strong PMS. From the pills I have tried it had the best effect on me. It stabilized my moom better. However, I would experience sudden extreme lows during pre-menstrual/menstrual period. My boobs got enlarged and tender and very painful during the first 3 months but these effects reduced to such extent that now on a 6th month they do not bother me. One of the most negative side effects I have been experiencing is spotting/bleeding outside of the period. Sometimes even for a whole month. After 5th month this seems to be getting better. Usually light bleeding starts around 5 days prior to my expected period. I have been experiencing severe cramps/pain during periods. But that has been there already before due to my diagnosis of endometriosis. Sometimes these effects do not get as present while taking the pill but it's very hard to draw a conlusion on that as they definitely persist.
