How do I stop bleeding that has lasted more than 14 days? What can I do? I'm pretty tired.

I started taking micronor in November 2022 because I was breastfeeding. The first month I took it, I didn't have my period. The second month I had it but the problem is that it has been going on for 14 days already. My cycle is all out of whack. I stopped breastfeeding and went back on the same birth control pill I was on before I got pregnant. I've been back on it for 2 days. My period is still going on and I've been bleeding for 14 days. I'm starting to get really tired of it.
