Flu-like symptoms normal?

Feeling thirsty, achy in my knees, elbows, shoulders, low back, neck, slight headache, tired, chills, very light spotting, and slight nausea. Feels like the flu.

Are these regular pregnancy symptoms, or maybe the start of an illness?

Very worried as I’ve had 3 mc in the past, one time I felt like this and did find out about a mmc a few weeks later.

Please respond, thanks!
