Weeks and days changed?

Question

So my due date is a Friday and I've always changed from X weeks and 6 days to X+1 weeks on a Friday, today it says that on Friday I will be 20+ 6 but I am 21 weeks. Why/ how has this changed and how do I change it back?!?! I've checked and my due date is the same.

Answer

A lot of people days and weeks changed with the last update. It's so annoying! I just had to move my due date up a day to keep on track.
