Hindi ka nag-iisa, mama! A few of us sa barkada ko felt the same thing around that time, parang ang baby ay sumasagot na sa movements mo kaya mas nagiging obvious lalo ang discomfort. The pressure and that bulging feeling is pretty normal sa second trimester dahil lumalaki na talaga ang baby at limited na space, pero para sure na lahat okay, best to mention it sa OB mo next visit para ma-check niya properly. In the meantime, try standing up every 15-20 minutes, stretch your pelvis, or use a pregnancy pillow when seated, sobrang tumutulong talaga kahit desk work lang. Hang in there, ang third trimester pa lang where sitting gets even trickier haha!
