Hi angela - I had the exact same thing last month - took Preganacare Conception and had a 53 day cycle - would never, ever use them again it totally messed me up!
Well ladies I am 13dpo temp still high, not real symptoms at the moment bar the odd twingy boob and stomach and more tired than usual- I had to take the day off yesterday because I was feeling poorly and apart from aggravated hayfever today am feeling pretty ok.
Am trying to hold out to 20dpo as I don't want to be disappointed but really, really want to POAS!
