Head cold and FET?

Has anyone ever come into an FET while not feeling well? I’ve had sinus congestion/pain, fatigue and headache for a few days. I know it’s not Covid, I get tested at work and I had my booster over 2 weeks ago. My lining check is Thursday, so my transfer wouldn’t be for 10 more days at the earliest, but it still worries me to go into a transfer not feeling 100%. Some of these symptoms are possibly side effects from delestrogen shots. Has anyone ever had these side effects? It’s my first time taking the shots. Has anyone gone into an FET not feeling the greatest and has success?
