Ay, congrats sa 30 weeks na! Pero honestly, yan is something you should definitely ask your OB about sa next checkup mo, bawat pregnancy talaga is different, at ang pusod behavior can vary so much, so better safe na lang na marinig from your doctor what's normal for your pregnancy specifically. A few of us mums talk about this, at iba-iba talaga ang experience ng bawat isa, kaya hindi ko masabing it's one or the other, pero the fact na nag-iiba from what you expected is worth clarifying with your medical team so you're not worried the rest of your pregnancy, yun lang.
