Second baby but everything about this pregnancy is different and it’s been 8 years🤦🏼‍♀️

I’m 35weeks 4days and my vag is hurting so bad, it feels like I rode a bike for hours and I’m sore from riding it😩 I haven’t gotten checked and I’m not sure when I will get checked but could it be a sign that baby will be here soon? My first pregnancy was nothing like this pregnancy, my body hurts so bad I can’t turn when I’m laying down, I can barley walk cause it hurts so bad down there. My baby is also pretty big last week she weighed 6lbs 13oz so that can probably be the reason I’m hurting to but my son was also big!!!!
