High Temp for Over 30 Days and Not Pregnant?

[ZoeyZoo]

I have only been charting for 2 months so I was hoping some more experienced moms to be could give me some insight.

I went off bcp a few months ago. When I started charting my temp was low and then shot up. I got my period on day 28. I am now 10 days into a second cycle (in a 28 day cycle) and my temp has been high for the last 30 days! I took some HPTs but they are coming out negative.

Any ideas on why it has been high for so long when I'm not pg?

if you are on cycle day 10, you probably haven't even ovulated yet. it is not the actual temperature that is important, but the shift in temperatures that occurs after O.

are you taking your temps at the same time? is the room temperature relatively the same?

Hyperthyroidism could cause this.

As could hot weather.
