Does progestogen-only / Mini pill cause weight loss?

I experienced some negative side effects when I first went on the pill (mood swings, headaches), both this time around and previously, but they dissipated/softened after a few months. My migraines have increased in frequency over the last 12 months, but I have been a migraine suffered since puberty.

Just started my third pack, originally I was on the combined pill (4+ years) but experienced some migraines so the GP switched me to desogestrel. The first week of taking I had a regular heavy period for 8 days ish and then was okay for about 2 weeks, then the breakthrough bleeding started and has been on and off for 4 weeks now, a mixture of red / brown spotting which is not ideal as I can't be intimate with my partner as its very off-putting. I'm due to meet with my GP over the next few weeks to discuss but I know they will just say this is bleeding is normal for the first few months of taking. I did notice some spots around my chin and mouth area about a month in, they have since gone. I'm losing weight purely because of my good diet and workouts but tis good to know I can lose weight on this pill. Unsure if I want to continue taking these.

I couldn’t be happier with this pill. After having a break from contraception and using FAM and falling pregnant twice, I decided I needed to go back on birth control. I initially tried the copper coil but it expelled after 24 hours and I didn’t want to go through the insertion process again. I went to the doctor and she’s said to give the mini pill a go, and I was prescribed Zelleta. I was really nervous as I have previously been in the combined pill for 7 years and it really impacted my mood so I was hesitant to try a pill again, but the doctor told me my body could react differently to the mini pill and she was right. The first two weeks I had headaches almost everyday, and was feeling extremely tired but I think this was down to my body getting used to the pill. After the three week mark they both disappeared. I had no loss of sex drive, I would actually say it’s increased which took me by surprise. I’ve lost around 8lbs and I feel like I have more energy. The only downside for me is my skin (previously completely clear) has had some breakouts but I will take it. My low mood and anxiety has decreased significantly. I was so hesitant to go back on the pill but when your doctor says they’re not all the same and you just have to find the right one for you, listen to them because it’s so true.
