I don’t know what to believe

So according to glow I’m 4 weeks today . However , on other apps ( bounty ) I’m 3 weeks and 7 days and on baby centre I’m 3 weeks and 7 days also .

They both have the same af dates but predicted that I’m different weeks .

I don’t know which one to believe , I have an appointment next week so I guess I’ll find out then , but has anyone else had this issue ?
