Cramping and pressure, normal?

A

I already messaged my doctor but I won't hear back until tomorrow AM. I've had cramping for the past 2 days. It lasts about an hour and comes and goes through out the day. Its not painful but its definitely there and some mild-medium discomfort. It in my uterus and vaginal pressure. I'm 15 weeks along. I think it's too early to be Braxton hicks. Just looking for some reassurance or suggestions. I am being watched for cervical incompetence so I just worry a lot.
