Heartbroken and just need to vent

I am 38 and have diminished ovarian reserve. We skipped over <a href="https://glowing.com/glow-fertility-program">IUI</a> based on Dr recommendations and moved straight to <a href="https://glowing.com/glow-fertility-program">IVF</a>. This is our first cycle. After 9 days of stimulation, we only have one measurable follicle at about 13-14 and about 5 smaller follicles that are all less than 10. The Dr said moving towards egg retrieval is not looking favorable and wants me to convert to <a href="https://glowing.com/glow-fertility-program">IUI</a>. Based on our previous conversation, our chance of a successful pregnancy with <a href="https://glowing.com/glow-fertility-program">IUI</a> was less than 5%. I’m just so sad and trying not to stress. If it doesn’t work, the doctor said he’s not sure yet what he would change.
