I woke up in the middle of the night last night with some mild cramping. They came every few minutes and it lasted for about an hour. The same thing happened a couple weeks ago too. I don't think they are BH because my stomach doesn't tighten and it doesn't really feel like RLP either. I have my 31 week appt tomorrow so I will ask the DR. About it then but I am just curious if anyone else is having this.
