Continuous period while ttc with PCOS?!??

My periods have ALWAYS been like this. They always come irregularly and last for 2-4 weeks. I just wanted to see if there was anyone else out there that experiences the same thing!😩 I’ve done medicated cycles and I’m on Metformin but none worked and I’m taking a break from doing medicated cycles…but it’s so discouraging having a period this long, I’m pretty sure I don’t even ovulate at all naturally bc of it😕
