Normal yan sa third trimester, mama! Hormones and the baby pressing on your intestines can definitely speed things up, at marami sa amin na nag-August din nag-experience ng ganyan, di mo kailangan mag-alala na hindi ka nakakakuha ng nutrients, the body absorbs what it needs kahit mas mabilis ang transit time through your system. Since you're maintaining your weight and baby's growing well according sa OB mo, signs na okay ka lang, pero just to put your mind at ease, might as well mention it sa next check-up especially if you're worried about the frequency or if it becomes painful. You're doing great with the fiber-rich diet to avoid constipation, that's really thoughtful, just make sure you're drinking tons of water din to balance it out, and try not to stress too much kasi stress itself can affect digestion din!
