Ate plastic

I feel like a terrible chin mom. Two days ago Tiquita ate the clicky top of a pen. I gave her some gas drops as a precaution thinking, it might help in case trying to pass the plastic caused gas. Well, she bit the tip of the syringe off yesterday! She's still eating and acting normally. I was hoping to get input on how long I should be watching her poops? Anyone know how long it will take to pass or how long until I see signs of blockage if it were to go that route? Do you think she'll be in the clear by friday? I'll be leaving town early Friday morning and won't be back until after midnight. Any suggestions on helping her digest/pass the plastic?
