Ay, don't worry mama, normal lang yan! At 27 weeks kaya may protective layer pa, hindi ganyan kadali masama ang baby from one accidental poke or pinch. A few of my mum friends din nag-share ng similar stories during pregnancy and lahat fine naman ang babies nila, pero since medyo makirot pa rin, siguro best check with your OB lang para peace of mind mo and they can make sure everything's okay, especially if may persistent pain pa.
