Ttc when you have a freaking head cold

So I had a failed <a href="https://glowing.com/glow-fertility-program">IUI</a> in january and decided to not get an another in February, we've been ttc for one year on 2/11. In december when ttc I had such bad laryngitis, and now this month on our own I have a head cold! It never fails! Everytime it's my fertile window when we're trying on our own, I'm friggin sick one way or another. It's frustrating and makes for an unreliable BBT. Anyone else have this happen to them, because I feel so upset and alone :(
