baby shower coming up, no friends to invite?

im pregnant and my oldest sis is also too. she wanted us both to do a babyshower together, and ask me if i have any friends to invite, but i realized i dont. i mean, i do have friends, but we dont even talk anymore, and its been hella long since weve talked. my sis is going to invite all her friends, while i dont have anyone but them. its because my hub never lets me have any social media, nor does he want me to go hang w my friends, unless hes there. but i never get to go cause i cant drive. he took away my freedom. anyways, i kinda dont want to do the babyshower w her, cause i feel like its gonna be awkward w all her friends there, while i dont have anyone but my fam. i think id rather just throw one myself w both mine and mine husbands family. what should i do? should i just do one w her or throw one myself?
