You could also start charting your temp at fertilityfriend.com. Basically u just take your temp everyday before you get out of bed and when your temp goes up most likely youre ovulating. You should prob get on the due in march or april boards they are very helpful. Just calculate what month you would be due in and go to thier board. there are a lot of hopefuls on those board including me. LOL!!!! Everything u need to know about charting and such they can tell you. LOL!!!! Well good luck and come over to march board if you want thats where I am.
