well, I'm deffinantly NOT an expert and I'm sure that a lot of girls can give you advice, but the best if to chart your temperature and cervical mucus. Use the basal therm. And take your temperature orally the second you wake up!! DON'T move before you take your temp. Set the therm. beside your bed and as soon as you wake up in the morning take your temp. before you do anything! Try to take your temp. at the same time each day! I know a lot of us used Fertilityfriend.com. Also remember to chart your cervical mucus too. The ff website also has a lot of helpful info. Hopefully this helps! And let us all know if you have any other questions!
