Very Very Confused. Help?

Lexi
So yesterday and the day before I had really strong positive opk's & by late last night my opk was negative. I BD'd with my DH last night as well & it felt like he was hitting my cervix. My cm seemed accurate but I honestly don't test it that often to be 100%. I took Clomid this cycle 100mg & CD 3-7. I was expecting my spike in temperature today but it does not really seem to be a spike.. I've never had this happen before. Any thoughts? Feeling very defeated right now thinking that I may not have ovulated this cycle.
