Temps can range greatly for all kinds of reasons. When you keep a chart you will notice the patterns. Take a look at my chart (as strange as it is this month)on fertilityfriend.com my login is tina11112 and password b308. I o'd yesterday. You will see the increase in temp. Also some dips and jumps b4. Like I said weird month, normal b4 d&c was 26-28 days. I think what happened this month(just guess)is right after I should have o'd my body realized it didn't o so it started a whole new cycle. At least that's my interpretation, lol. Feel free to look at it or look at other charts in chart gallery.
