Progestogen-only / Mini pill and nausea or vomiting

After years of being on no contraception I decided to give the Mini Pill another go. It worked for me several years ago but began impacting my mental health so I stopped. This time round I have been more in tune with my body. The first 3-5 days I had itchy nipples. I’ve gained 4kg in a month and my diet hasn’t changed. I have had a headache and neck pain since day one, if I didn’t keep on top of pain relief it would come back. I already have acne prone skin which has took years to get under control and within the first week I developed cystic acne. I’ve felt myself snapping at others in my house over silly things and also felt unable to make decisions. They say to give it 3 months to settle into your system but it’s a no go for me. I cannot deal with the daily head and neck pain, acne and mood issues - so back to condoms we go.

Everything seems ok only issue is that period has fully stopped. Unsure if i should be concerned.

Constant low mood, lack of energy and motivation, brain fog, bloating, cramping most of the month, breakthrough bleeding data 10 - 22 of pills for 3 months.
