Sick with cold before BFP?

Kb

my first pregnancy (mc) i had a slight cold a couple days before i got my positive test. I'm 9dpo and I've had the whole stuffy nose/cough/sneezing thing going on since 7dpo. Has anyone had these symptoms before their bfp? I feel like crap and hoping it means something. I've read it can be from your body lowering it's immune system, My temps are still rising.
