Aw mama, yan ay common especially sa first trimester, pero mas okay na siguro i-check mo with your OB just to be sure, baka low blood sugar, dehydration, or something pregnancy-related lang na kailangan ma-manage properly. A few of my mum friends had similar experiences and okay lang naman sila once na-adjust ang eating habits nila, like smaller meals more frequently instead ng big meals, pero talaga, better safe than sorry with these things kaya go na sa doctor para ma-ease your mind!
