Should I get my cervix checked at 36 weeks?

Your cervix's dilation and effacement might be checked every week starting at week 36 (or earlier!), or not until week 38 or 39, or your OB might not do a vaginal exam until you're in labor.

How dilated should I be at 36 weeks?

The Mayo Clinic reports a woman can be dilated 2cm to 3cm for several weeks prior to delivery, which means your cervix can dilate at week 36. Without other labor signs present, such as effacement and contractions, the dilation is something you can discuss with your doctor, but it shouldn't be cause for alarm.
