Blood sugar

So I had GD in pregnancy but didn't need medications. I had my baby last month. I still have to take my 2 hour glucose challenge.

I have noticed my fasting numbers on the higher side after delivery. Between higher 80s and 90s range. Could it be since I don't get the best sleep after baby?

When I was pregnant they used to be in 70-80 range typically.

Today my fasting was highest of 99 after I was up for an hour feeding and sitting up my baby. I am really concerned

Also after some high carbs meals my blood sugar was 147 after 1 hour after eating chicken wrap, mini pizza, 1 oz chips, half a slice of cake and 120 after 1 hour eating Whataburger and half fries.

Are these indicative of prediabetes? Anyone cleared the type 2 diabetes test with such numbers? I am scared to do the 2 hour test but have to do.
