How do I change my weeks/days for pregnancy???

Katieann

When I first found out I was pregnant, based off my LMP I was estimated to be due around April 6th but when I went in for my first U/S the due date changed to April 9th. So now on my glow app the weeks and days continue to be off by 3 days and I’ve already changed the EDD but it hasn’t corrected?? The nurture app is correct but the main glow app just isn’t.
