Braxton Hicks contractions at 18 weeks?

[Roskva]

For the past couple of days, I've been getting a sporadic lower abdominal crampy feeling, and my bump goes hard. Is this just Braxton HIcks, or should I be ringing my MW? I'm only 18 weeks along, and that seems a little early for Braxton Hicks.

Braxton Hicks apparantly do start at about 11-12 weeks, but due to the small size then you don't tend to feel them until later, so don't rule out BH.. Any concerns though you should speak to your MW, even if it is to put your mind at rest

I've been getting them since about 10 weeks with this one, it is my third though!

This one is my second. I know I started feeling Braxton Hicks fairly early with dd, but not this early!
