Can It happen any day???

So went to get my ultrasound done today to check my my fluid levels and it’s at 8.5 they say it’s a normal low so Not really worried but was just told that baby girl is in the birth position and is really really low I know a lot of women carry low but a week ago she was pretty high and now she’s low and I can feel it and I’ve been having some sharp pelvic pian and some cramping not a lot my nurse told me that she doesn’t think I gonna make it to my due date it’s so uncomfortable to sit walk laid down and pressure and I have to pee all the time 36 weeks and two days can this happen any day now??? I’m scared but I am happy I’m just a mess right now really emotional !!!! 2 baby
