Mommy, please check with your OB agad kung masakit-masakit talaga or if you're worried, hindi worth the stress, okay? Around 16 weeks, some cramping and stretching sensations are pretty normal as your baby grows, pero if it's sharp, persistent, or may other symptoms (like spotting or heaviness), better safe than sorry na mag-consult. Every pregnancy is different, so your doctor can give you peace of mind. Lean back, stay hydrated, at take it easy muna while you wait for your appointment. You know yourself best, trust your gut.
