Ok so i came off the pill mid pack (I now know this wasn't the greatest idea, and should probably have waited till end of pack). I was 8 days into the pack and took my last pill 4 weeks ago. (No withdrawal bleed)
My question is, how do I know when/if i'm late and to take a test? 
I took a test last week after experiencing prolonged cramping & mild nausea, which came back negative, but a week on and I'm still experiencing the same symptoms, but no sign of AF!
Is this just a case of playing the waiting game and a weekly test unless AF makes an apperance? Or are there some guidelines?
Thanks in advance!
