Help!

So I'm 39 weeks and three days and I have felt my baby drop extremely low.  Witch makes me happy but I woke up today with my pelvic area super sore. It's extremely uncobferitble to sit . It hurts but I feel like it could be worse. My pain tolerance is in the higher side . My question is has this happened to anyone else and I'm I going into labor here soon ? This is my first baby and I really want to meet him but don't want to get excited if I have to wait a couple more weeks. I'm unsure if I have had contractions either. My cat also is on a freak out too I feel like he feels him coming.
