We are extremely lucky to have conceived so quickly

We are extremely lucky to have conceived so quickly. My husband and I started trying a little over 3 weeks ago. I tracked my bbt most days and was quite sure when I ovulated because I had unilateral abdominal twinges and a spike in bbt during my fertility window. I got the stomach flu two days ago and symptoms haven't subsided, so I decided to test (even though my period isn't due for a week) and it was positive. I think paying attention to my body and bbt really helped. This app is pretty awesome!
