Ay congrats sa baby! Normal lang yan sa 7 weeks, yung dizziness, back pain, at sobrang antok ay common pregnancy symptoms, pero since it's your first time and you're worried, mas better talaga to check with your OB just to be sure everything's okay lalo na kung ang hilos ay medyo malakas na. A few of us sa mom group namin had similar concerns early on, and ang doc namin assured us it's part of the journey, pero important talaga na ma-monitor sya properly kaya mag-book na ng appointment if you haven't yet!
