Braxton Hicks contractions

So, this week we're at 38 weeks, and I believe I had my first early contractions last night. I walked about 30 blocks in the morning and lifted weights at lunch, and while we were watching our Netflix, I felt these sharp jolts of discomfort from my lower pelvis through my vagina. They continued on and off for about an hour, and they weren't painful, exactly, but jarring. They sort of stopped my breath altogether. Jen, my work friend, says this is probably the beginning of my cervix opening up. I guess we'll find out on Friday, at my next visit.
