Aw mama, yan ay common during pregnancy, lalo na if you're in your second or third trimester, ligament stretching and the baby's growing weight can cause that cramping sensation, but kailangan mo talaga i-check with your OB just to be safe, especially kung persistent or painful na talaga. A few of us din nag-experience ng ganitong side cramps, and most of the time it was round ligament pain, pero better to confirm with your doctor para walang alalahanin ka!
