Hi There, I Am Currently 7 Weeks 1 Day Pregnant

Hi there,

I am currently 7 weeks 1 day pregnant through IVF and I am taking metformin 1500mg a day for PCOS and Endometrium vaginally 300mg a day and Estrace twice a day. I am suppose to go off all of these three meds at 10 weeks. What are my chance of miscarry? The reason I ask is because last time I was pregnant I was taking all these meds and once I was 4 weeks 4 days pregnant the doctors asked me to get off of metformin and the ultrasound showed that the embryo had stopped growing at 6 weeks 4 days... could that had been from me stopping metformin?

Please help me!

Thanks
