Sudden stop of CM

I’m 5 weeks 2 days and CM has been thick and clear or white. Suddenly last night it’s not as thick as it was. I’m so scared of another ectopic. Last time I had an ectopic it was dry the entire time and I felt so dizzy and constantly had to run to the bathroom, couldn’t keep any food in me.

This time I’ve had occasional slight nausea and constipation, and am increase in CM until last night. I’m going for blood work to check on my progesterone levels.

Anyone had a decrease of cm and still pregnant??
