NST or no? 36w5d

So I am debating weather I should go tp get an NST done or not.. Yesterday my baby girl was getting in her 10 kicks in an hr but I guess I was feeling a little concerned because she was getting like 20ish in almost an hr when typically she will get almost 30 in half an hr. I chalked it up to her just not being in an active mood tht day.. So fast forward to today, normally when I wake up she's moving a bunch [I guess trying to tell me to eat 😂] Well she was moving but nothing compared to her usual. So, I get up and some fluid leaks down my leg [Might be TMI but I dnt wear panties at night, just my pj bottoms cuz i dnt like anything squeezing against me] soo I couldnt really get a good look or smell of it to tell if maybe it was pee but I feel like regular discharge isnt tht runny? Anyway, Ive been very light headed this morning but Ive been drinking my water and ate breakfast but dnt get why I still feel this way. Should I go to get an nST or wait it out to see if she picks up more on her kicks the rest of the day?
