Uy, don't worry kasi yan talaga ang anterior placenta, parang shield muna ang baby from your tummy so the movements feel more muffled, like pintig-pintig lang talaga instead of the usual kicks na parang gumagalaw na malaki! A few of us mums sa barkada namin na may anterior placenta, ang sabi nila that by 24-26 weeks mas naramdaman na nila ng malinaw, so soon you'll feel more defined movements na hindi lang pintig, pero honestly, since your OB said normal na, you're good, and every baby (and every placenta position!) is different anyway. If you're still worried by week 25-26 and hindi pa rin mas malinaw ang movements, just mention it again sa next check-up para peace of mind mo lang. Congratulations sa 22 weeks, mama!
