Ang EDD discrepancy na yan ay super common, lalo na kapag may weeks gap between ultrasounds! Yung pelvic ultrasound early sa pregnancy (aug 10) ay usually mas accurate kaya yan ang priority, pero the BPS one sa aug 22 might show slightly different dating dahil sa growth variation ng baby, some babies are just naturally ahead or behind, hindi iyan alarming. I'd definitely bring both results sa OB mo at let her decide which EDD to follow, kasi siya ang makakapagsabi ng accurate based sa lahat ng factors, lalo na kapag may health considerations ka.
