35 weeks - pelvic pressure/pain

I'm 35 weeks and started experiencing INTENSE pelvic pressure this week. It's slowly getting more painful while doing activities/walking. I know this is a sign of SPD. I have a doctor's appointment tomorrow and will obviously bring it up then, just curious if anyone else experienced this at this stage? Does it ever indicate that labor may be coming sooner rather than later? Part of me mentally is hoping it means baby is planning on a little bit of an early arrival, because I truly don't know how to get through the next five weeks, especially of work, with this new symptom.
