At what stage does Braxton Hicks get worse?

Today I was getting bad period type pain or feeling at certain stages where I felt like I was just about to get my monthlies, I even had to run to the toilet to make sure nothing had just happend if you know what I mean. It kind of got me worried as I have 8 weeks left and worried that maybe labour was starting but I'm sure it was just Braxton Hicks. I never had it bad with dd so its kind of all new to me. So does anyone know at what stage in the pregnancy does the Braxton Hicks get worse or more intense?

sorry cant help you out on this one. i have 3 weeks to go and have yet to get a BH (that i know of anyway) just wanted to say hope you are ok, and if you are in any doubt there is no harm ringing the maternity ward of your hospital.

I've been getting that every night for a week but I'm just at the start of my pg
