AM I OUT

I took a opk which confirmed ovulation. Well on the day I ovulated I got a Major cold! Runny nose, aches, and sore throat! So I’ve been taking over the counter medication, today I feel much better but on my two most fertile days I acquired a cold out of no where, I think ovulation May have been the culprit! I read online that a cold can stop a person from getting pregnant? Is this true? Has anyone else ever conceived even while having a cold?
