Do you think it's okay to drink while pregnant, when you know you're having a termination?

I am 5 weeks pregnant, and having a termination due to complications with cysts on my ovaries and fallopian tubes. I've had a big weekend planned for a long time this weekend, and I really would like to drink alcohol. Do you think it's okay to drink alcohol while pregnant, when you know you're having a termination? Or should I obstain completely?
