Hay nako, anak, tummy pain in early pregnancy is quite common, but since it's been ongoing, kailangan mo talaga magpatingin sa OB mo as soon as possible, okay? Better safe than sorry lalo na ngayon ka pa lang 6 weeks. A few of my mum friends had cramping in the first trimester and it turned out normal, pero iba-iba talaga and your doctor needs to check if everything's okay with baby. Huwag maghintay pa, book an appointment or go to the clinic this week, ha? Keep me posted, okay?
