Does it matter WHEN you are sick in relation to when you ovulate that tends to sway girl? For example, I am sick now with a stomach virus and I'm on CD 7 today. I only had diarrhea once, no vomiting, but I did have fever, chills and body aches yesterday. My symptoms are resolving today so I will have been sick about 48 hours. So, is it being sick any time in the cycle before O that sways or being sick through O or a couple days prior?
