Millinette 20/75 pill and headaches

Within 48 hours of swallowing the first tablet I started to have Brown discharge which has grown into what would be described as a full on period with horrendous stomach ache, it will be 2 weeks on Sunday since I swallowed the first tablet. I'm assuming this is the breakthrough bleeding and my body needs to adjust but anyone else experienced this?

Millinette gave me full blown acne and made me a lot more teary which is so unlike me. Initially, I was on Rigevidon for 2.5 years, stopped as I experienced breakthrough bleeding/didn’t need it. Discovered I had major brain fog on it, and my thoughts / perception on dating became a lot better once off it. Decided to try Millinette based on that as I got into a new relationship, tried it for 3 months as advised. I’ve not always been spotty, I get hormonal breakouts but that’s it. I’m happy and healthy otherwise! Millinette made me start to break out in hormonal spots - on my forehead, chin (especially) and cheeks (which I’ve never experienced before). It was making me miserable! I also noticed how much more teary I’ve been lately - as if anything slightly upsetting can make me cry. I’ve been using differin (a retinol acne gel treatment) and it’s helped slightly but not much. I’ve also gone up an entire cup size, and my breasts are slightly achy all the time. I also have experienced headaches when I came off the pill for a bleed - I now take it consecutively because my body seems to react badly to the drop in hormones. I’ve stopped Millinette now, and based on a nurse’s advice I’m going to try Yaecella. I think my body/skin reacts badly to the progesterone in Millinette/with pills that have less oestrogen in them. Hopefully Yaecella works (it’s a new generation version of the famous Yasmin pill). I’m 21, 5’10 and 57kg if that helps too!

Not a great pill for PCOS. Within a couple of days my skin broke out like crazy, I started sweating so much and after a while noticed my body hair was growing faster again after being on Yasmin for a few years (ended up going back to it). I also was seriously depressed and very emotional on this pill all the time, sometimes unable to even get out of bed.
