So the past two days I've woken up to a horribly painful numbing sensation, that literally makes moving any direction impossible and worst. I called my doctors office yesterday and spoke to a nurse who said I should be fine since there is no spotting or bleeding but the pain is excruciating. what can I do to ease the pain or at least make it subside or something.

PS. I'm 18.1 weeks and the pain is in my pelvic and lower tummy area. But it's not gas or constipation
