Can stomach flu hurt my chances of getting pregnant?

I took a trip to Mexico City with my husband last week and was super sick on the plane ride back. Took about 4 days for me to feel better and now I feel like I still have the bug in my system as I still have indigestion symptoms. This past week was also our fertility window and we tried a few times. Could this stomach flu hurt our chances of conceiving? This is our second cycle trying.
