Ate, alam ko ang worry mo especially dahil may history ka ng ectopic, ganyan talaga ang anxiety! But please follow up with your OB closely kasi siya lang makikita ang full picture ng ultrasound and PT results mo together. At 5w6d, sometimes ang gestational sac ay hindi pa talaga visible sa transvaginal, so your doc will likely want to recheck in a few days to confirm everything is progressing normally. The meds your OB gave you and the thickness ng lining, lahat yan ay things only she can interpret properly based on YOUR situation. Stick with your scheduled follow-ups, and if you feel anything off (cramping, spotting, anything concerning), message your OB agad or go in for peace of mind. Kaya mo yan, mama.
