37Weeks vaginal pain! Can't sleep.

Dolores
I am 37Weeks and last night was a rough night I was having some really bad Braxton Hicks and only got about 2 and 1/2 hours of sleep. Well today my vagina has been throbbing and hurting (as if I had rough sex). I took a warm bath and while in the bath I felt as though I needed to pee. I tried and tried to get out of the tub but was unable to before I 'peed' I continued to try even after for about 10mins all the while still feeling as if I was peeing. After finally getting out I went through about 5 panty liners but then it stopped... but now the pain and throbbing is worse and I am having irregular contractions and lower back pain and can not sleep. There is no leaking and as far as I know I have not lost my mucus plug. So my question is am I in labor, and/or should I go to the hospital? I don't want to go unless it is time.... please help...
