Combined pill and headaches

I didn't start it on day 1 of my period. So this month I got my period anyway. I went to my GP (who prescribed it to me) and we determined it's my period due to timing, consistency etc. Good to note however that since I took it to control menhorragia. 10 days into taking it, my cycle lengthened to a week (minus spotting) and it's a lot less heavy than I know it. I'm hoping to feel better next month and thinking to skip the placebo entirely but I was told it can lengthen the spotting/breakthrough bleeds. There doesn't seem to be a right or wrong. Just trial and error then adjust. Note : Don't take it mid cycle. Take it as they tell you day 1 of your period. I did this because of severe reasons at the time and was also very sick. I hoped it would prevent the usual mess. In a way I succeeded somehow, just not the way I'd have liked. But then I'm too hard on myself too.

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
