Cervix check

Today I had my 36 week 5 day cervix check and my doctor had a student with him today and he let her check my cervix .. she put her finger in my butt and she thought it was my vagina and it was too awkward at the moment to tell her it wasn’t. So then they told me to get dressed and when they came back in I told them she checked my butt for dilation and she said she didn’t so my doctor didn’t recheck. 🤦🏽‍♀️ so according to my butt hole I’m not dilated at all
