Labor??

9•20•16💙 • Mommy of 3😊 Expecting our 4th 💙
Since about 7:15pm I noticed contractions... When I wasn't really busy I counted 2 in 30min and I kept feeling them but didn't keep track. I took a hot bath.. And it didn't stop them (which I heard happens with BH) they got really painful after midnight.. I'm still having them.. What to do???
