Pressure!!!!!!

So I'm 34+3 days and I've been having a lot of pelvic pressure over the last few weeks. This is my second full term pregnancy and baby is very low. But tonight the pressure woke me up from a dead sleep! Like I've peed 4 times in the last 30 minutes and had a bowel movement. I did go into spontaneous labor with my older son but I'm just wondering if this is the start of labor? Should I be worried? I don't go back to the Dr until next Monday
