Choco, it's probably the BBs kicking. When u lift up your shirt, u can see like little crawls or something poking out, very fast actions. And sometimes even hiccups too. Whwn that happened, I can feel my tummy rocking from side to side, all jiggly.
For Braxton Hicks, u can feel them coming, at least for my case that it. I suddenly have the urge to pee or poo poo and before I know it, i can feel my tummy tightening and then it scrunches up, very hard when u touch it. But this hardening gradually subsides after 30-50s or so, then all is calm and I can feel my BBs moving about. I was concerned enough to see my gynae cos during the past week or so, I'd been experiencing it quite regularly, like every 1-2 hours. When I was in my 19th-24th week, I had already felt this but back then, it only happened like twice a day and when it first happened, my hubby and I were still so thrilled and excited cos' we always thought that our BBs were poking their butts or heads out to say 'hi' (when my tummy scrunches, the hardening is like a ball). But when the frequency became higher in my 24th-25th week, being the paranoid MTB that I was, I called my gynae who asked me to rush down to see her. That's when she put me on CTG and found some contractions.
Read up on BH these few days, and surprised to see that most articles say that it's quite common even in the 2nd trimester, so long as it doesn't happen too often within an hour. But guess that gynae is concerned becos' she said that multiples tend to be problematic so must err on the side of caution, before the BH develops into full-blown contractions which are painful which often lead to dilation of the cervix.
Are u sure that u feel hardening in your tummy? BB movements are well, movements, But the hardening is unmistakeable and usually last about 30s or so before the hardened area relaxes and becomes soft again.
