7 periods in 3 months?

Lee

I've recently gone on the implant (like 5 months ago) and I know that it's normal for your periods to be a little weird for a while, but this is seriously ridiculous.

I've had a period every 2 weeks. I have PMDD and the implant has done nothing to really help my hormones, so I've been going through really bad PMS every week. I'm tired, I'm sick of it.

Has anyone else had this/ know what could be causing it?
