Mini Pill almost constant breakthroguh bleeding 8months

[hwilliams260]

I've been on cerezette/cerelle for around 8 months now. My periods have always been irregular even before I came on the minipill. However, ever since going on it I'll have no period for say a 30-40 days and then i'll end up having light bleeding for 3 weeks. Then it might just be 2 weeks and then more light bleeding. Obviously this is very frustrating- I've booked an appointment to change my contraception to the implant that goes in your arm but I'm worried I'll have the same problem if not worse.

Any Advice? Should I be sticking this pill out for longer?
