Clomid Troubles

Meaghan • Mommy to Ainslee - Our sweet, little, IVF miracle baby. Born March 2016!
So today is cycle day 33 for me. I thought AF would arrive Friday but still has not shown up and I have been absolutely miserable for about a week. AF cramps and super sore boobs. All BFN. Has anyone else experienced late AF while taking Clomid? I thought Clomid was supposed to be a sure thing and help regulate things. So confused and frustrated.
