What's wrong with me?

Weeks I've been having hard time keeping food in(not from vomiting) I'm literally always needing to go after meals I give myself 20 minutes top to be ready to hold the bathroom hostage.

It's been only a week after discovering we were expecting but now I'm like is this normal?

I go back in two weeks for a checkup because my nurse thinks I'm way over 5 weeks.

I drink water frequently but am still feeing constipated mostly throughout my days.
