Need advice please! 5th IUI fail.

DL 👩🏻👨🏽‍🦱💉🌈💙

Hey all, so today is 13d post 5th <a href="https://glowing.com/glow-fertility-program">IUI</a> and It appears it was unsuccessful and I just don’t know where to go from here. My husband wants to do another natural cycle. Here’s our brief history. Also, we’re using a donor.

<a href="https://glowing.com/glow-fertility-program">IUI</a> 1 - natural; chemical

<a href="https://glowing.com/glow-fertility-program">IUI</a> 2 - natural; chemical

<a href="https://glowing.com/glow-fertility-program">IUI</a> 3 - natural w/ progesterone suppository & baby aspirin; bfn - I went in the day after positive OPK so pretty sure we missed it.

<a href="https://glowing.com/glow-fertility-program">IUI</a> 4 - letrozole, aspirin & progesterone; bfn

<a href="https://glowing.com/glow-fertility-program">IUI</a> 5 - switched donors, letrozole, aspirin & progesterone; bfn

Blood test is tomorrow but I’m not getting my hopes up. Any chance it won’t show on a blood test til after 14dpiui?

Should I try another natural cycle?

Should I ask for US monitoring? Or, test for endometriosis? I have no symptoms but idk what other tests there are. Everything else has come back normal. I have an autoimmune disorder that causes inflammation but it’s in remission and the specialist says it’s not linked.

Any ideas? What worked for you? I’m not even sad I’m just at a loss. Please help!
