First time taking clomid help!!

It's my first time taking clomid and I'm so confused.  I normally get a positive reading on my Opk... Well normally I get one high fertility day and then the next day is ovulating.  Well I have now gotten 3 high fertility days in a row and have yet to get peak day.  I'm not sure if this is normal bc it's not for me with out medication... Is this normal with clomid? Has this happened to others and you still receive peak day??
