Trying IUI

Nina • Mother to a wonderful 7 yr old boy. 40 and pregnant 💜💜💜. Suffered 3 miscarriages and one passing at 15 weeks from Trisomy 18. Keep Hope 💜
So my husband and I went to the fertility clinic yesterday to get  our results from all the lab work and procedures (HSG, ultrasound, etc). Our Dr said that all labs were normal and we were healthy. She diagnosed us with unexplained infertility. The next step will be 50 mg of Clomid and IUI. I am wondering who has been through this process? Any concerns or suggestions for me? I am excited but Dr said there was a 7-10% risk of twins!! Wow - my poor husbands eyes popped out of his head. Lol any feedback would be great. Thanks !!
