Help!!!

So the past couple of days ive been getting really weird pains low in my stomach and near my hips, frequent need to urinate and have a bowel movement. Moody, really bad back pain and sore head. Ive tested and all are negative. Ive got PCOS and absent periods but have sex regularly with my husband every 2-3 days as we are TTC.

Can someone please give me some advice? Xx
