Hi Dr. Sher thank you for your time. I’m 45 mother of 2 -18 &17 yr olds(normal pregnancies) I been doing IVF for the past 3 years. I’m currently on my 8th treatment with sperm & egg donor. I’ve had 1 chemical pregnancy and a miscarriage in December 2022 of 13 weeks. I’ve had test EMMA-ERA-ALICE done along multiple ultrasound of uterus and blood work done everything has always been normal. I always create a very good endometrium over 12 with 3 grade A layering yet we don’t achieve embryos to stick. The embryos quality have ranged from a 3-6 day frozen embryo and from A to C quality my A’s never implanted my B was the chemical pregnancy and the C was the one that reached 13 weeks. I don’t want to loose hope but at this point my Dr’s can not figure out what is wrong or what other test/exams to request. What can I do? Please help.
