Uti while pregnant

I am about 6 weeks pregnant and I believe I have a uti. It is the worst ever. Horrible pain when I move let alone use the bathroom. I told my manager that I need to call my doctors when they open and he told me that I cannot leave 😔 anything I can do so I can get through my 8hour shift without feeling like I am dying and having to run to the bathroom every 30 seconds. I am drinking cranberry juice and a bunch of water but it isn't helping
