Well I had my follow up HSG today after having my tubes untied in september. Both tubes loot great wide open. I ask the doctor if the rumors were true that I ah e seen online, that a hsg can have a roter-ruter affect and make you more fertile then normal and he said yes it can. It can break any thin scar tissue and remove gunk and mucus plugs. Good think I ovulate tomorrow or Saturday.....I'm one happy lady.
