Mama, kahit common yan sa pregnancy, kailangan mo talaga i-check ito sa OB mo next visit, o kung sobrang sakit na, mag-urgent care ka na lang para sure. Maraming reasons pwede yan (ligaments stretching, posture, muscle strain), pero OB lang ang makakapag-assess ng tama. In the meantime, try resting, warm compress, at proper posture, pero huwag mag-self-treat pa lang habang hindi mo nasiguro. Stay safe, okay?
