Bleeding on mini pill

I had my baby in March and got a Depo shot before leaving the hospital. I would spot and bleed every 2 weeks so I didn't wanna continue the shot.

By July I would spot to bleed lightly every other week, then all the time. Went to the obgyn and she gave me a mini pill.

I've been taking it for 2 weeks and no change in spotting/bleeding. She also prescribed an estrogen cream to go into the vagina. But I didn't use it because I was constantly spotting/bleeding.

I went back and told her. She said it's normal for being on the mini pill. The estrogen cream warns against using while bleeding. So I don't know what to do. Anybody experienced constant spotting/bleeding after stopping the shot and getting on the mini pill?
