Sick during TWW?

Has anyone had a pregnancy where they had a cold/flu during the two week wait? Husband and I had a condom failure this month (exact day of O'ing), which would be okay, but then I happened to get sick right away. I had a low grade fever for a few days, violent coughing, and took cough suppressants, and fever reducers. Has anyone had the same experience with a pregnancy? Should I be concerned about the health of the fetus if I am pregnant? I'll know in a few days.
