Hey mama! Congrats sa baby! Para sa peace of mind mo, alam ko na scary ang ganitong feeling, kaya please visit your OB agad para masigurado na lahat okay, especially since ito first pregnancy mo. They can check properly at ma-ease ka talaga.
A few of us moms felt different things during early pregnancy, so walang one-size-fits-all, pero ang safest ay marinig mo talaga from your doctor kung ano ang normal for your case. Take care!
