What does labor feel like realistically?

I want to know how early and active labor felt for you. I've been having contractions and I'm 2-3cm dilated, yet my midwife said I could still be looking at delivering a week or so from now. I'm a little nervous I won't know when it's truly go time, I'm supposed to go to the birth center when contractions are 3-5min apart.

They feel like really strong period cramps that come in waves, but are a little random I'm not sure how I would time them. I have intense pressure in my pelvis and lots of back pains. Hope I'm getting close!
