Hi everyone, This is my first time posting a question here, so I apologize if I break any rules. This subreddit has helped me tremendously and although it sucks to be here, its the best worst place to be. So thank you all for your endless support.

My flair explains most of it, but just to clarify on a few things and then my question. I started IVF in August 2017, got 7 embryos, had a fresh transfer immediately after, and then two frozen transfers (single embryos only) in Nov 2017 and then most recently on Jan 18 2018. I did not do PGS testing because when I asked about it, my RE said she typically does not recommend it below the age of 36. After my first FET, my beta hcg was 65, two days later was 32. My RE said it was probably a chromosomal abnormality, so the embryo was eliminated. My husband and I both did genetic analysis (karyotypes) in January after the second failed transfer and they were normal. My Vit D was originally low and then rechecked in January was normal. So was my thyroid.

So, here I am. My RE was really optimistic at my first FET, which didn't work. Now I've had my second FET, no dice. My lining is fine, my hormones are fine, the embryo apparently "looks" good but certainly that doesn't mean anything. The plan this time is to now transfer two embryos because I've had three failed transfers. RE wants to repeat a sonohysterogram (had one two years ago which was normal) and endometrial "scratching" a week before I start my next FET. From what I have read, it seems to improve pregnancy rates, and the risks are minimal. I currently control my cycle with birth control, then use a combo of estrace, endometrin twice daily, PIO at night (lucky me!), baby aspirin, and prenatal vitamins of course. I'm assuming we will do a similar protocol this next time.

My question is, what else should I be asking them to do? How can I be proactive? Sadly over the years, I have become very complacent and do what they suggest without asking because I feel so defeated. I asked before the last transfer about the ERA, my RE said she has only done it a few times for patients on request and that there are no studies showing it adds a benefit. Anything else? Is hysteroscopy beneficial? Via ultrasound, they have seen a 1 cm polyp, but other than that, nothing.

If nobody has an answer, that is okay. Thank you for letting me vent and thank you for your suggestions.

EDIT: thank you for your responses. It seems like a hysteroscopy would really make sense. Some of my test results are not currently available to me so I am going to ask the Doctor about the previous polyp they found. Thank you all so much.
