Has anyone seen my period?

I have never been on BCP's for more than 6 mos at a time (I'm a rebel). I took them this last month to reduce the size of my cyst on my right ovary and stopped on Saturday. I figured my period would resume no later than Monday and I could start my next cycle. It's now nearing the end of Tuesday and there is nothing....no spotting... no cramps....no bloating...nothing. That would normally be a hallelujah moment but not this time around. If I don't get it by Thursday, I can't do this cycle due to a business trip that lands during the time frame of my approximate insem dates. Why does this have to be so difficult? I wonder if I'm going to get a period at all this cycle. Has anyone else gone through this before?
