Two periods on the pill!

Charlotte 🇬🇧 • Mummy to 2 beautiful little girls. Born 2016 and 2018.

I'm on the contraceptive pill and have a period during my 7 pill free days. However, I also bleed halfway through my cycle, usually around 12-14 days. Its always as heavy as my regular period, often with cramps/ acne. Why is this happening!?
