I have been charting my BBT for 8 cycles now. This cycle my temperature has risen noticably, however I still have not had a positive result on my ovulation tests. I am on day 20 of a usually 29 day cycle. I have done an ovulation test every day since day 14, all of which have been negative. My temperature rose above the cover line (36.35) on day 19 to 36.4, and this morning, day 20, it rose to 36.7. I am confused and would like some advice/help.

I think I may have a short leteal phase (averaging just 9 days) from when temp rises, with spotting usually starting two days before my period. I have been on the SSRI Citalopram since Feb 07.

Many thanks
