Waking up with extremely tight belly

Katherine • Pregnant with first baby with my hubby!!
I'm 34+2 days and I woke up this morning with a really tight belly, it felt very delicate and like it would be painful if I were to touch it 
Is this contractions or from the baby kicking all night in my sleep? 
Not too worried about it, just curious 
Also random question I have an at home Doppler babies head is down 
And the heart was almost above my pelvis when I found it this morning 
Does that mean he's dropped??
