Super dark urine

So that past couple of days i have been cramping really bad while going pee and this morning I went in to do a urine sample and my pee was super dark with a red tint to it I've been feeling super sick and have had some more pain I'm 16 weeks and I'm just worried I called my doc and they don't have the results and the nurse I talked to doesn't seem to know her was from a hole in the ground... has anyone else expreianced this?
