Had my baby/ overbearing ogyn HELP

Hey ladies ! Had my sugar baby on 1/25. 🥰 shes 6lbs and 14 oz. They told me before I had her, she'd weigh about 8lbs and in the 80th percentile on our ultrasounds but she came out smaller than expected. I was on 2000 mg of metformin for fasting numbers.

I did have a question. My ob kept testing me throughout my entire hospital stay for blood sugar levels and they always came out perfect. She is insisting that I keep testing once a day for two weeks and come back on my 6 week appointment to do a 2 hour test. She seems certain I'll be on metformin even though, I've passed everything. How do I deal with this ? Even my hospital nurses are confused. Not only that but when I told her I wanted the pill or patch, she kinda dismissed me and said I should get an IUD. I told her what if I dont have insurance or something down the road and it needs to come out and she was like ...uhhh.. planned parenthood? Lol she has been like this for awhile. I told the hospital my birth plan was to formula feed and everyone was respectful of that except my ob. She insisted that I at least try to breast feed before I give the baby formula. I've tried formula feeding with my first, it wasn't for me. I feel like I'm powerless in this situation. What do I do? Btw i did stick to formula feeding because I'm very adamant about this and the nursing staff backed me up.
