Aw, mama at 37 weeks + 2 days ka na, so you're almost there! Luya is safe naman and maraming moms use it para sa discomfort, pero if the belly pain is nakakaworry or getting stronger, better check with your OB agad lang, mas safe na sigurado muna siya kung ano talaga ang cause, kasi may ibang things din na pwedeng mag-cause ng pain near delivery. One of my mum friends had similar mild cramping na normal lang Braxton Hicks, but she still got checked para sure, at mas natulog siya ng maayos after!
