Did I mess up with timing here... what do you think of my chances?

Heres the thing about the charts, they are just averages, I always have a 28 day cycle, my periods are always the same length, when I was TTC my son all those charts said I would ovulate between days 14-17 in my cycle, I must have ovulated somewhere between days 4-7 though, because my period was only 3 days long, I only had on days 4 and 5, I was sick the rest if the month/cycle, and yet I got pregnant,lol, as for drinking I would drink as little as possible, as you can never be 100% this early on if your already 1 week pregnant or 1 day, not until you miss your period, best wishes
