Ay anak, mas safe talaga na i-check mo yan sa doctor mo right away, lalo na kung tuluy-tuloy at malakas ang sakit, better to be sure, di ba? A few of my mum friends had similar experiences at iba't ibang reasons pala, kaya important talaga i-assess ng medical professional. Tingnan mo rin kung may ibang signs, like bleeding, spotting, or unusual discharge, at i-report mo agad. Praying it's just normal pregnancy aches, but don't wait, call your OB or go to your nearest health center. You and baby need to be okay.
