Late af on letrozole?

its.whatever • Pre health student👩🏽‍⚕️ Truth makes people mad😁

Is a late period normal on letrozole? I ovulated 15 days ago and no sign of af. I had cramping the day before and nothing the day of and my fertility clinic is closed now till the 2nd of January 😩I know It’s only a day late but I’m used to every sign of af coming like mood swings and cravings and cramps but this cycle nothing😩
