Ay, alam ko yan! Maraming pregnant friends ko na nag-experience din ng ganyan, lalo na sa early weeks, ang hormones talaga nag-aayos pa, kaya parang ang buong body mo nag-o-overheat then nag-o-overproduce ng sweat sa hands and feet kahit malamig pa lang paligid. Mine got better after the first trimester kaya normal lang yan, pero since you're only 5 weeks pa, best talaga to check with your OB just to be sure everything's okay with your blood pressure and hormone levels. Drink lots of water, wear breathable socks, at try to stay cool, pero seriously, mention it sa doctor mo on your next visit! How are you feeling otherwise?
