is it possible to just swell in one hand with PE???

i'm 30wks tomorrow and ive woken up this morning with my right hand swollen i could only just get my ring off, it hurts to close my hand into a fist and i have that constant tightness feeling in my hand, I have no signs of anywhere else swelling so dont want to rush to the hospital if im just over reacting

any advice right now would be appreciated!
