Hi mama, light cramping sa early pregnancy is usually normal talaga, pero yung feeling na parang gutom or acid, honestly, better to check with your OB para sure, kasi bawat pregnancy is different at gusto natin walang alalahanin mo, di ba? A few of my mum friends had similar sensations early on and it turned out fine, pero some were dehydrated or needed to adjust their diet, so best na i-confirm with your doctor agad para peace of mind mo. Congrats sa buntis!
