IUI or IVF

Lindsay
I need advice. I had a miscarriage at 15 weeks a month ago that broke my heart. But we are willing to try again. We did three <a href="https://glowing.com/glow-fertility-program">iui</a> and were successful on the third, which was a medicated cycle. At this point would you recommend doing another <a href="https://glowing.com/glow-fertility-program">iui</a> or move on to <a href="https://glowing.com/glow-fertility-program">IVF</a>. I'm 36 and my partner is 38. This will be our first child. I feel conflicted because we were successful with <a href="https://glowing.com/glow-fertility-program">IUI</a> but I'm worried about all the time that is going by. We have been TTC for three years. 
Thanks for your input. I go to see my fertility doctor in July but just am looking for advice from other ladies. ❤🌈
