2 failed ICIs with frozen sperm, time to try something else?

Hey! I know this group isn’t super active but I’m hoping to get some opinions. I tested negative this morning at 12dpo on my second cycle with sperm from a cryo bank and I’m almost 100% sure AF is showing up any minute now so I’m starting to think of the next cycle.

I originally decided to go through a bank even though it is expensive because I appreciate the security it offers in term of the donor having no rights. But now I’m leaning toward trying to find a donor through the known donor registry or justababy app to increase my chances of success (more sperm, cheaper, and fresher). I think I will need to find a lawyer to write up a contract or something? Getting stuck coparenting with a total stranger is my actual nightmare, if he should change his mind at any point I want to make sure I have all my bases covered.

Can anyone offer me any advice/reassurance about this? Have you successfully used either kdr or justababy? Should I just bite the bullet and keep paying for frozen sperm and hope for it to actually work?
