Cytotec and what to do

I know I keep posting and updating my situation so I'm sorry if you see my posts a lot lately but since comformed missed miscarriage yesterday, I talked to my doctor and he had given me cytotec to take but no painkiller. So I called back to request one and they are closed for the weekend. Pharmacy says its okay to take Painkillers over the counter. I just want to know if it's worth waiting until Monday for him to get me painkiller or just do without. I'm 6 weeks and already bleeding without taking cytotec and no cramp.
