Clomid & late period?

Ok...ok...the heading looks obvious but its not as it may seem. Took 100mg clomid this cyle. On Fertility friend, it didn't draw a coverline, so have been confused over whether or not I actually ovulated. Am now up to CD 41 and have had a few BFN's. Am beside myself...either want a BFP or for my period to come...help!
