so confused!

So I was supposed to ovulate yesterday, however I was down all day with a low grade fever 100.4-100.9. I got sick 3 times starting at 4 a.m. I have irregular and longer cycles that I have yet to figure out. I can see myself being the one who gets a bfp and says it's impossible because all my data doesn't add up. btw, were still ttc no. 1 we are laid back and go with the flow about it at the moment. anyway I just used the Lou and noticed light spotting? no cramps or anything and I feel much better. Was this just a bug or does anyone have a similar bfp story?
