Uy, yan talaga common sa pregnancy, lalo na around that time! A few of us mums had it din, some couldn't even sit comfortably, kaya mo yan, pero definitely check with your OB para sigurado, baka kailangan mo ng specific stretches or posture tips na safe sa 4 weeks. In the meantime, try pampering yourself with rest, matibay na pillows for support, at yung iba sa circle ko swear by warm compress (hindi sobrang init ha). Kaya mo yan, mama!
