Braxton hicks or something else?

Samantha
I'm 39 weeks today. And Tuesday I got my membranes stripped and Wednesday I lost a huge amount of what appeared to be my mucus plug, ever since then I've had mild cramping and losing lots of mucusy discharge every time I go to the restroom. It's either clear, brownish or red. Currently I'm laying down and have literally had what I think are Braxton Hicks every 2-3 min with a mild cramp. Are they BH or something else??
