Looking for some advice
Long story short, I have unexplained infertility. When trying naturally I had 2 chemical pregnancies where I pretty much bled in day 1 of expected period, it would arrive on time given a positive test.
We then exploded the ivf route, my first fresh resulted in a chemical and then had a frozen which also resulted in a chemical.
We had a meeting with the clinic who advised we pgta our remaining 2 embryos before the next transfer.
They advised against NK cell testing as they don’t support the protocol and that there’s not enough evidence to suggest it helps.
They said the other option is to have a uterine biopsy to look for infection.
What would you do in this situation? I feel like everything’s a gamble. On one had I don’t want to experience a loss again on the other I don’t want to put stress on my embryos going through an additional thawing process.
I’ve had a lot of testing done including karyotype and everything is fine. It’s frustrating not having answers
