Helppppp!

34 weeks today- I know I post about this a lot. I know. But I seriously think this may be it. So all day today I've been weakish and achy, had a few small BH contractions, then tonight while at the store with my husband, baby was all in my vagina kicking and pulling on nerves and what not, then just now I was trying to eat and I literally ate maybe 20% of my plate before having to run to the bathroom (for a #2), and that's the second time for that today, but this time I felt some weird movements from baby super low in my pelvis, and got constipated half way through, but still had the urge to go. So far still no mucous plug, bloody show, or water (that I know of), but I know not all of it happens to everyone at the same times.. Could this be it? Should I be preparing?
