Combined pill and nausea or vomiting

I was tri-cycling this pill and passed a a decidual cast after the first 6 weeks with no bleeding ( was not painful to pass). My periods were lighter when breaking between 3 packs. I did get some breakthrough bleeding during my second tri-cycle. I had really tender breasts in the first few months with some breast enlargement but that passed and no other issues.

Zero libido and very painful to have sex when I tried. Stopped periods which was great for endometriosis but slowed my digestion so much the bloating and endo belly was uncomfortable all the time, caused pain in hips, lower abdomen and lower back. Had constant reflux unless I slept upright which wasn’t ideal.

I started the combined pill Drovelis late in my cycle. On day nine of taking the pink pill I got a breakthrough bleed. It's been 10 days and it only increased the last maybe 4 days. I am currently taking iron though and since I'm using it mostly to manage menhorragia im hoping the breakthrough bleeding will taper soon. In contrast my periods were terrible. Dragged over 12 days. Haemorragic. I never went to hospital for them in years but probably barely saved myself on time. I also had them every 26 days which was less than ideal so timed apart. Its worrying but I'm told to continue and see how it goes into the next pack or I'll have to consult with my GP and consider changing brand if my situation doesn't improve. My moods are terrible. I get crying spells and am a lot quieter than I used to be. I'm usually outgoing and very opinionated. Might review again next month. But since it's my first experience I thought id give it a shot
