Pill after miscarriage

👧🏻
Hey Everyone!
I miscarried in June and my period returned on September 4th as it took 2 1/2 months for my levels to reach >5. They caught the miscarriage right away.
My first two periods were 28 days apart but this one came a week early at 21 days. When I saw my doctor she mentioned putting me on the pill to reset my body. She didn't want to do this but said it was an option. Did any do this and have success? She would put me on it for 3 months and then I know I'd have to wait a month to try. I just don't want to wait that long but if it's better for conceiving than I will! Thank you in advance!
