Momshie, malamig tyan and frequent burping ay normal talaga sa pregnancy, lalo na pag lumalaki na ang baby! Ang digestive system mo ay medyo slower na during pregnancy kaya nag-eentrap ng gas, at yung hormones din ay nag-aaffect. But since ito yung first pregnancy mo at gusto mo maging sure, better ask your OB about it sa next visit, para ma-rule out any concerns at ma-ease ang mind mo, lalo na if may other symptoms ka. Ang few of us moms, kami rin experienced to during 2nd trimester, so you're not alone, girl!
