“What is wrong?”

I am having weird symptoms and not sure what is the cause. My period was 5 days late, although this could be due to high stress and weight loss. My normal weight is around 115 and it got down to 102. But besides that I am having pain in my vagina and the inside walls are very swollen. Excess discharge that was normal at first then turned slightly yellow. I also am having tons of spams/twitches in my stomach (they don’t hurt just annoying) the muscle spasm sometimes happen in my legs or arms but mostly stomach. I was having actual pain in my thighs when laying down to sleep like an aching pain but haven’t had it is a few nights. I know I am not pregnant because I am not active and even took two tests just to completely rule it out and it was negative . I can’t get checked out for at least a week and am very concerned. Any potential diagnosis?
