First-time Wearing Contacts, Third Day In, Vision Constantly Blurry?

I got my first pair of contacts (Acuvue Oasys for Astigmatism) three days ago, and I still can’t see to save my life. It feels like halfway between my previous glasses prescription and no glasses at all. I’ve worn them for maybe 4 hours on Friday, 5 hours on Saturday, and maybe an hour so far today. Can it really take this long for my eyes to “adjust,” or do you think they messed up the Rx or grabbed the wrong ones? I know I don’t have them in the wrong eyes. I have a follow-up appt. next Fri. but maybe I should go in sooner?
