Just feel ugh

I got some yucky cold like a month ago and still can’t shake the cough and just general crappy sick feeling. Doc said my chest sounded fine and suggested allergy meds but they’re not really helping. Hard to tell what’s pregnancy blah and what’s the remnants of this cold. I need to start walking and exercising a little but I just can’t get motivated when I feel so crummy. I was told not to take EmergenC which is my usual “kick this crud to the curb” go-to. Any pregnancy safe energy solutions to get my ass to the gym? I’m 8 weeks.
