Diva Cup with Bath Bombs?

I just realized that I'm going to be on my period when I go on vacation next week (ugh). The hotel room has a jacuzzi tub and I've been planning to go to Lush and get some bath bombs and take a bath every night I'm there to try some new ones out. My bathtub at home isn't too comfortable and doesn't have those lovely massage powers, so I've been looking forward to this jacuzzi. I use a diva cup and was wondering if it'd be ok to have in with the ingredients of bath bombs. Would it possibly be ok with bubble bath? Has anyone else tried a few bubble baths with their menstrual cup in?
