Er visit?

I'm not really sure what's going on with my body. I just started the mini pill 2 weeks ago. I am not sure if it has anything to do with what I'm going through. I have been experiencing badd lower abdominal pain for about a week. I discussed with my doctor and he told me if it didn't get any better by Thursday to call him back. However it's getting worse and it looks like I might have an infection somewhere because my urine is different it's extremely cloudy and look shiny. I know it's not due to dehydration. Not sure if I should go to the emergency Room to get checked or if anybody is experienced anything similar. Any advice is great for think you
