At 37 weeks, swelling sa pelvic area kasama ang difficulty pooping ay medyo common dahil sa pressure ng baby at hormones, pero hindi talaga dapat maging ganitong problema, kaya mas safe na i-check mo ito with your OB para ma-rule out kung may infection or constipation complications. Para sa ngayon, drink lots of water, eat fiber-rich foods, at try mag-walk kung kaya mo, pero I really think doctor visit is the best move para ma-ease your mind at ma-address properly.
