‘Unexplained’ infertility 🙄

I went to see a infertility specialist at the end of March because my SO and I have been trying for over a year. Over the last few weeks I’ve done a water ultrasound to check my uterus, and a HSG where they take a look at my tubes and my SO got a semen analysis. So, the water ultrasound was normal. As for the HSG they said the results were normal but mentioned my left tube didnt have much spillage or dye at all versus my right which had a lot, so I guess the right is doing way better than the left but they still ruled it as normal 🤷🏽‍♀️. Today I went in to the specialist for my follow up and they told me the results of my SO’s semen analysis, he has low morphology and motility which is 2% and it needs to be at 4%. I also had my blood checked and I have low vitamin D, so now I’m taking 5000 IU a day. Today she said she didn’t want to just blame it on the male factor as to why we haven’t conceived yet and that she is going to rule it as unexplained. She said we have about 5 or 6% chance of conceiving naturally and she suggests <a href="https://glowing.com/glow-fertility-program">IUI</a>. I couldn’t help but just feel depressed, I’m only 23 years old but I want to hope maybe a miracle can happen and we can conceive naturally before we just have to get the <a href="https://glowing.com/glow-fertility-program">IUI</a>. 😕
