When should I take a late AF from???

Hello everyone. Bit of an odd question, not sure if anyone can help. Every month, for the past 5 months or so, my AF arrives on a different CD, only within 2 days different. For example, last month was CD30, month before CD32, Month before CD33, CD31..etc etc... So what cycle day should I use to say when AF is late?! Hope that makes sense! Thankyou for listening. Good luck to all those TTC! xx

I would go with the longest cycle. I assume you want to know when you may be able to test. Your other choice is to use an Ovulation Predictor Kit so you'll know exactly when you ovulate. Then you can test at least 12-14 days after that.
