Iui again or ivf?

Ti

Hi I am going to be 40 in February and we’ve had three early miscarriage and two chemical pregnancies over the last two years. We’ve tried <a href="https://glowing.com/glow-fertility-program">iui</a> three times now and they’ve all failed. One ended in early miscarriage. My doc wants to try <a href="https://glowing.com/glow-fertility-program">iui</a> one more time again but I’m wondering if we should go straight to <a href="https://glowing.com/glow-fertility-program">ivf</a> to maybe even consider surrogacy. We had two miscarriages tested and they were both normal. I have unexplained recurrent pregnancy loss. So frustrated 😣😣
