It won’t have much impact on your partner, as his sperm were produced about 70 days ago, LONG before he got sick. It may have an impact on you, as illness can mess with your hormones and cause you to ovulate early or late. As long as you timed things the best you could, you did your best and all you can do is wait and see. Make sure you’re staying hydrated and avoid cold/flu meds just incase. Also, congrats on being able to bd when you’re both sick — I bet that was the last thing you felt like doing! Such dedication! Good luck!
