Nervous.... thoughts?

My husband had a SA done in August. Count was 26 million with 2% morphology. My OB overlooked the morphology and caught it before my US last week but said I should still be able to get pregnant. I had my first IUI on Thursday and before he put the sperm in he didn’t tell me an exact count post wash but said he was putting in a few million sperm. I didn’t think to ask for an exact number. But a few could me 2, 3, or 4 if that. Now I’m nervous it won’t be enough. I did have a MC beginning of Sept with Femara/trigger/TI. I don’t want to stress over this but now it has me thinking. Thoughts? Success stories with low counts? My OB did put extra in my vagina, my husband said if he didn’t think there were enough he wouldn’t have done that part?
