I was wondering if anyone else has experienced this - I am 6 weeks pregnant and have been having what I can only describe as the dull ache you get just before your period arrives. In fact, that's what I had been thinking it was until I did the pg test. It's not all the time but does last for hours. I had a dating scan yesterday and baby is fine and with a heart beating etc, so am not unduly worried. Sonographer said it might be just the growing of the baby. Didn't have it with my first, however.
