Mama, kahit mild lang ang sakit, please don't wait, message your OB ulit or go to your nearest clinic para ma-check lang, especially kung first time mo to at 11 weeks ka pa lang. It's better to be safe, and they can give you peace of mind agad. Marami sa amin nag-experience ng random aches during pregnancy, pero kailangan talaga i-confirm ng doctor kung normal lang or kung may kailangan i-monitor. Hoping your OB gets back to you soon, but in the meantime, try resting and hydrating, and if the pain gets worse, don't hesitate to go to ER na. Praying you're okay, mommy!
