Cramping At Night?

[Kay_]

I'm 37 weeks and 4 days, last night around 1:30am I had pretty bad period like cramps to the point where it took me awhile to fall back asleep again. Throughout the day yesterday and maybe the day before that I had mild cramping as well. However last night It lasted around 20-30 minutes. Has anyone ever felt this before? Normally I would just have the sharp shooting pain when I walk fast or for too long, this is my first time experiencing these cramps...
