Weaning off IVF meds

My fertility doctor was nice enough to squeeze me in for one last scan at my 10w mark yesterday since my new OB scheduled me until early April. Everything with baby is great and my progesterone levels are good at 13.5. She stated I can stop all medications at this point but I’m a little scared. I’ve Googled what progesterone levels should be at 10w and it says anywhere between 10-44. I am definitely on the lower side of that and I’m actually concerned. I know the placenta takes over and makes it’s own natural progesterone starting at week 10 but just wanted to hear any of you ladies stories of successful full term pregnancies after going through IVF and weaning off all medication cold turkey.
