37w4d.. what should I do?

37w4d with baby number 2 already have a scheduled c-section for June 9th but I was checked 3 days ago and I haven’t dilated any and cervix were still mid.. but for 2 days now I’m having awful cramps in my lower stomach around in my hips and back so bad I can feel it in my legs to the point I can hardly walk , Tylenol isn’t helping (Wednesday my OB told me to just continue taking the Tylenol but I also wasn’t hurting like this then). My feet are extremely swollen and I can hardly keep anything down even with using phergan gel (my OB gave me a prescription for the gel per my request, I have a 2 year old and the pills make me too sleeping and I’m allergic to zofran) anyway I’m literally in tears and shaking from hurting so bad.

Should I go to L&D even though I feel like they won’t do anything... or wait till my next OB appointment on Wednesday?
