Tailbone pain?

I’m 21 weeks and at my job I have to get on the floor and back up every 5-10 minutes and it’s HARD. Just walking I will get this sharp tense pain at my tailbone area and it’s so sharp I’ll drop what’s in my hand at the time. It don’t last long but will go on all day.

And getting up and down off the tile floor is becoming harder and harder which I’m half way done I get but I’m not that big yet so I’m struggling with not being able to keep up so any tips? 🥺

This job is so important to me so I don’t want them to think I can’t do it.
