First Timer

Okay so hubby and I are fixing to go through an iui Cycle. Currently waiting for AF so we can get a baseline u/s and then start meds. I’ve only ever taken Femara with no luck ovulating, so we will add follistem and a trigger this time and do iui if all goes well. I guess I want to know what to expect, I see people saying they test out the trigger a lot, is that something I should do? Give me all your info and advice ladies! I’m nervous and don’t have super high hopes but staying cautiously optimistic.
