Just chart to confirm ovulation and nothing more. Stop after you see 3 or 4 days of sustained higher temps. Otherwise, you'll think you see implantation dips, or you'll be worried that af is coming, even though it's not. It'll drive you mad! So, in addition to good temp taking techniques (consistency, patience, good physical habits like eating well, exercising, getting enough sleep, etc), don't read too much into charting your temp. Sooooo many things can affect your temp and you'll drive yourself crazy trying to figure them out. Remember, you're looking for trends, not individual temps. I just got my bfp last week, and this month, I stopped taking my temps after ovulation. It was so freeing! Good luck!!
