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?
