Provera and HSG

Today I am starting my first dose of provera. I will take it for 10 days and then hopefully get my period within a week after. Once AF comes I will have an HSG test done between cd5-10. We’ve been trying to conceive for a year with no luck and I knew I was the reason, my cycles are so irregular. My last AF was Dec. 27-31. I’m just wondering if anyone has every gone through this process? I’m not sure what to expect. Just praying this will work and God will bless us with a baby 🙏🏼❤️
