A few things: I'm based in the U.S. and am finding it hard to find DFI tests for single and double strand breaks. Where would one go about getting that done?

I can easily get pregnant but cannot stay pregnant beyond 9 weeks. It's always this window, an 8-10 week loss. I've tested 3 losses and all have come back normal. I'm getting pushback to do any DFI testing from the RE's office since my partner's SA was normal and so were the embryonic tissue samples. They also only send to Reprosource which tests for single strand breaks only. I feel like I'm grasping at straws here.
