Stopping ivf meds

So my re had me stop my ivf meds at 9 weeks 1 Day he also released me to my obgyn since all my bloodwork and ultrasounds have been great. The last ultrasound I had the baby was moving and looked like she was waving! She has had a healthy heartbeat since 6 weeks! I’m just nervous bc you read online how ppl say they had miscarriages bc they stopped progesterone in oil and other meds. I know I have to trust my dr he knows what is best for me. I guess after being on all these meds for all these months I’m scared not to need them. In ivf you get so used to all the meds, injections, dr visits that I guess I’m just nervous. Has anyone else gone off the meds around 9 weeks and everything was ok? Thanks!
