Cold/flu-like symptoms 5dpo?

K.N. • ICU nurse :)
I am 5dpo today and I woke up early this morning (wee hours of the morning) with a sore throat. Once I got up and around it didn't get any better, and I feel like i have been hit by a truck. My cervix was low-medium yesterday and today I can hardly reach it. Anyone have these symptoms and end up being pregnant?
