i've been having BH all day, and it'll cause pressure in my vagina, and i start to feel it on my butt also. i'm a first time mom so i don't know what to do and clearly need help. i've been tracking them and they last about 20 seconds. every 3 minutes? should i go to the hospital? i'm terrified. i don't wanna go, just to be sent home. 
also.. when i change positions, like i'll lay on my back they kinda calm down ..
