Next question...I'm not educated about trigger shots and stuff but that is to make you ovulate right? So if you ovulated with the trigger shot and you were only 4 weeks earlier this week then that is still early...sometimes you don't see a heartbeat until after 6 weeks and if you have a slow grower at first then you never know.
Don't give up hope hun! If there was growth then that is something to hold on to for the time being!!
What the heck? How much did it grow? Refresh me...how pregnant are you? If anything I would FOR SURE ask for a repeat ultrasound before any d & c happens. See how much bigger this jellybean gets by next Friday.
