Lost mucus plug, could this be it??

So last night i went to bed, having had B-Hicks contractions for the past day or so feeling rather uncomfortable over all. I was woken up at 11:45pm with the WORST pain ever! It was very sharp menstrual cramp pain that radiated throughout my whole lower stomach and was teeth clenching as I had no idea what was going on! I did some relaxation, but was just caught so off guard and drowsy/confused that teeth clenching was the quickest response. It last what felt like awhile and i tried to move, but it hurt, so I waited. Then I tried again, and although painful, I got up to go to the bathroom (felt a lot of pressure in my pelvis too, thought maybe I had to pee?). It still hurt and was a little less sharp and more crampy, went pee, went back to bed, was able to relax a little bit better through the last of it, and fell back to sleep. Waking up several times that night to sore, uncomfortable, crampy tightening all throughout the night. I was tired and didn't bothering timing them as they seemed pretty random, one or two with some lower back pain as well. I did NOT sleep well. It was very uncomfortable sleep-tossing and turning, achy and crampy tightening....just overall icky. Then I woke up this am with a lot of hip pain, overall uncomfortable and crampy/achy so i got up before the alarm. I felt like i had to poo again and had to pee, so sure enough, at 6:45 I went to the bathroom and lost my mucus plug. I am still getting contractions about every 10 minutes, some more uncomfortable/sharp than others, and tightening. I also have been to the bathroom 3 times so far this am...so this could be it...MAYBE. Or just another bout of false labor?!!? I certainly hope not I can't handle that again!

Could this be it? Or just more false labor? :(
