What to take when u have a cold?

Jackie
I have been ttc for 3 months now. Just got my peek fertility yesterday. I also woke up with a nasty sinus cold! I was going to take something over the counter but didn't want to mess with my ovulation. Does anyone know what is safe to take when you are ovulating that won't mess with it? Don't want to ruin my chances this month. Thanks and baby dust to all!
