Braxton Hicks.

I think I may have just has my first Braxton hick contraction. (Sorry) it was just after an orgasm, and suddenly my stomach felt funny almost, buzzing and really tight. Like a spasm. Then when I felt it, it was rock hard and a funny shape. It felt so bazaar! Uncomfortable, but not painful at all. Just really weird. I'm 25+4 weeks.

Anyone here where it's not your first pregnancy....

Is this a Braxton hick?

And if it is....is this what actual contractions start off like?

Thanks ladies.
