Waking up with contractions

Christelle
So this has happened 2 times now. I wake up in the middle of the night with contractions that come every few minutes but then it stops and I fall asleep. It's been over four years since I gave birth to my daughter so it's hard to remember exactly what they feel like but these feel like what I remember feeling. Whenever it happens I start to think oh gosh is this it! I'm almost 33 weeks.
