Newbie to charting

Hi!

This is my first time posting in this forum, but I've spent quite a long time lurking around and learning lots! DH and I decided to start TTC last month after almost 5 years of marriage, and had planned to do the whole "if it happens, it happens" approach. Now that we've made the decision though, we're both pretty keen to make things happen as soon as possible..:p

I have started charting my cycle, but after being a bit sick for the past few days, my chart is showing that I've already O'd - on day 8 of my cycle which has to be wrong as I've got a 30+ day cycle and my body is usually pretty good at showing me the signs. This is my chart below, if someone wouldn't mind having a look and telling me what they think? (Sorry, I don't know how to insert it properly)

Should I keep charting for the rest of the month or has this thrown the whole thing out?

TIA :)
