Mine was at 15 weeks. But not everyone gets BH. Just uncomfortable like the other ladies mentioned.
I'm 28 weeks mine started around 26 weeks. Feels like light cramping in lower back similar to menstrual cramps. Also feel my tummy tightening. Showers seem to help me!
Mine started at 16 weeks this time. Mine make me short if breath, my heart pounds and I get an adrenaline rush then my uterus tightens and my belly is a hard ball...some hurt and some don't...this is my 3rd baby, I'm 26 weeks now.
I started have them at bout 22w I'm now 25w tomorrow. Mine have been slight pain for a bout a min then stop. Feels like cramps or bad gas on ur stomach. Everybody's pain feels diff. But it's nothing u can't handle don't worry urself too much. U will know when u feel them trust me. I have them at least 2x a week just ur body practicing for the big day. I'm due aug 19th so I still have a long way to go lol!
