Dog chewed up pads and ped them, throwing up bile now..?

My 4 year old chihuahua got into a packet of feminine pads three days ago and he ped them yesterday, not like entire pads but a few bits and pieces. I can't believe I left them in a reachable place, Im so worried and mad at myself. I thought that he was fine and I know throwing up bile isn't regularly a huge issue but now i am a little worried.. its 7pm and my vets closed- i don't want to rush him to the animal hospital if im just being paranoid. He pulled a paper plate off the table today and was in his crate for a while so its possible he could've just been hungry, i don't know for sure, i guess im just worried. Should I take him or not?
