The 2 week long period

Gina

I'm in my mid 30s and my period normally lasts 3-4 days. however, the last 3 months it's been increasing in days... 7 days, then 9, and now this month I'm going on 2 wks!

I've had lab work done but all my results come back normal and my doc cannot figure it out.

Has anyone else experienced this?
