I think I'm going crazy!

So i had a mc/chemical and the bleeding started 14 days ago. I normally O around cd 12 but this cycle is sooooo off!!! I temp throughout the day (just like seeing the temp) and in the morning i have my post O temps but it changes during the day going up and down. This is the first time my temps did that so I'm not really sure when I O'd because it could have been earlier. Now cd 14 I'm having a lot of the same symptoms i had when i got my bfp last month.
