First IUI today.. Feeling really unsure..

Hey all today was my first IUI. I feel absolutely sick. I was really positive this morning but my day just seem to get more and more stressful as it went on. When DH went to give sample it was quite small sample and once washing was done showed to be quite low and also sluggish. All though this journey it's always been me that has the fertility issue and now as soon as it's going right for me. His slow down. So we went ahead and then got a call that my nan was sick and I am her carer so have to stay with her the night which makes backing up the IUI with intercourse really difficult. I just feel defeated already :-(
