Sperm analysis

La

Hi ladies, wondering if you can help me. Back story is I've had two mcs, one in Oct 2016 and one in May 2017. Been ttc ever since and nothing. Recently referred for fertility investigations, full blood work, ultrasound, day21 test, RH tests, std tests all came back normal. Hubby got his test results today, everything in normal range. Our GP can't see me until 13th of May but I have no idea what the next step is. He mentioned <a href="https://glowing.com/glow-fertility-program">IUI</a> before, do any of you know if there's a criteria for that on the NHS? Also wondered if I should ask for a HSG or a endometrial scratch? I'm happy with the results but feel a bit lost now x
