Oo naman, yan na sign na malapit na syang bumaba into the pelvis para sa labor, it's called lightening at very normal sa ganitong stage! A few of us here felt the same thing around 36-37 weeks, parang ang baby mo naging mas mababa, tapos mas okay huminga kasi hindi na sobrang pressure sa ribcage. But since you're already past 36 weeks, best to check with your OB para ma-confirm kung talaga na ngang engaged na ang baby at wala nang concerns, mas peace of mind ka lang, lalo na kung first time mo!
