Uy, normal talaga ang discomfort sa 37 weeks, ang baby mo ay malaki na, yan puno na ang belly mo, kaya walang comfortable position haha! A few of us tried at the end of pregnancy at ang consensus namin is hindi talaga enjoyable, plus the pressure and heaviness makes it painful para sa dami. The best thing is to listen to your body lang, kung masakit, tell your husband na kailangan niyo ng adjustment o maybe take a break muna, walang pressure! Para sa peace of mind though, best to check with your OB if the pain is sharp or unusual, kasi may conditions like placenta previa or other issues na kailangan i-rule out, and they can give you the all-clear or adjust kung ano ang safe para sa inyo two.
