Clomid & late period

DM

For those that have taken Clomid, did it make your period late and if so, how late? My doc said to wait 14dpo and if I haven't started my period, take a pregnancy test the next day. That would be today and I just got a BFN. I'm curious if the Clomid will push my period back even further... my normal pre-Clomid cycle is 26 days. Today is day 28 for me right now. Thank you!
