What's going on? Possible tmi

Idk which group to post this in but...here goes.

I'm a FTM. I gave birth to my son 4 and a half months ago. I bled for 2 weeks, then stopped. My dr cleared me at 6 weeks. A few days after my checkup, I began bleeding again. I assume it was my period. The thing is..I have been getting a period LITERALLY every 2 weeks since then. Moderate flow lasting 3 to 5 days.

To add info....

I was put on the mini pill immediately after giving birth. I have also been ebf until 2 weeks ago.

I knew my periods were going to be crazy pp, but is this normal?

I ALSO HAVE ANOTHER ISSUE.

My breastmilk has dried up. Idk if it's because of the frequent periods or something else. I've tried boosting my supply with pumping, increased fluids, oats, and latching. Nothing works. I've had to start supplementing with formula.

Basically, I have too much flow in one department, and not enough flow in another.

I am looking for similar experiences, advice or words of wisdom.
