Hubby being selfish or am I being dramatic

Megan

So I am preggo with my 3rd baby and it's a high risk pregnancy because I have been diagnosed with IC (incompetence cervix) . However, I am living in socal with my family's for help and going to school, but my hubby lives in norcal and comes on weekends of possible. Friday I am going to get my cerclage placement which is the stitching of my cervix that requires a little surgery my husband was there for our 2nd babies cerclage placement however he is saying he can't call in sick to be here for my current cerclage Friday the 6th. I really would like his support considering this rodeo is some painful shit and I can't really be with my other little ones. I have great support with family but I feel like I should not have to beg my hubby to be at a minor or major surgery. He takes days off for dentist appointments and to fight stupid court tickets but it's a big deal for me and the cerclage placement. Should strong arm him or just be quiet.
