Hi Sophie!
Normally, if the temperatures stay in the same range, it means you didn't ovulate this cycle or haven't ovulated yet; BUT since you had an IUI done, I would think the doctor checked to make sure you did, right? Maybe it's just a slight shift in temperatures and it's hard to detect the change, or has there been any inconsistencies in when you take your temperature in the morning?
If you're using fertilityfriend, maybe you can post your chart here so we can take a look at it :-)
Yes, but i think i did ovulate bc my temperature dropped, and dropped by 0.9? and the opk gave me a positive??? thoughts?
