Frustrated and need some support

Courtney • 37 years old, married with stepkids. BFP with 🌈 after first IUI and due October 2017!
TTC for 9 cycles. Did three rounds of Clomid 50mg and was unsuccessful. Period is due in two days and I think I can feel cramps starting. DH went for semen analysis today. I think I'm going to have to get HSG test to see if my tubes are blocked. Just so frustrated...
