I had my Ovidrel trigger shot on Monday and had back to back IUIs yesterday and today. I'm not sure if Dr. Braverman told me to start tonight or tomorrow night with progesterone(it's been a very crazy day...). I e-mailed him a couple of hours ago but he hasn't responded yet. I'm pretty sure he said tomorrow night, but I just need confirmation Do you girls know on what day I should start using them?
