Hey mama! Congrats sa pregnancy! Honestly, yung lower right side pain ay pretty common sa 7 weeks, a few of us went through the same thing, and it's usually just ligament pain kaya as your uterus grows, the ligaments stretch and it can feel really uncomfortable on one side lang. Pero important talaga na i-monitor mo siya, kung walang bleeding at it's just mild discomfort, usually okay lang yon, pero mas safe pa rin na i-mention mo sa OB mo during your next check-up dahil they can rule out anything else at give you peace of mind. Some moms recommend getting a maternity support belt around this time too, helps a lot with the cramping! But definitely touch base with your doctor about it just to be sure, lalo na if it gets worse or may bleeding na. Wishing you a smooth pregnancy!
