Sounds like Braxton Hicks. I've been experiencing them since early on as well and i'm already 32 weeks and get them almost every day
Yea I know it's crazy and my stress level has been very high due to different circumstances
All these can be signs of labor. I'm 36 weeks now and have almost identical symptoms. It could be nothing or could mean that your labor is approaching..
I'd call your doctor's office and let them know. Since you are still early into pregnancy, they'd prob want to check you.
Don't stress yourself, as I was saying could be nothing.. But its still best to check
