Ay, kakaibang reaction lang yan ng body mo sa pregnancy, mama, hormones and the baby pressing on your digestive system can really speed things up! A few of us pregnant friends namin noticed similar changes around mid-pregnancy, kaya hindi ka nag-iisa dito, pero 4-5 times daily sounds a bit frequent so definitely worth mentioning to your OB just to make sure walang iba pang factor like a possible infection or tummy issue, para you can have peace of mind.
