Hiya - apologies for posting and running! I've been off eating for two in anticipation of my imminent pregnancy 
In response to queries about poas'ing, I did so quite obsessively from 7 dpo (I know I KNOW insane!) through to 13 dpo (well 14 dpo if I'm honest!) at which point it was all over for me. I'm pretty sure I ov'd on cd 10 (standard day for me, with all the usual signs) and the SWI marathon ended on cd 11. So by 14 dpo if you haven't had the bfp you're out of the running! I fully accept that I might have got my ov date wrong, but following the shagathon it took me about another week to get DH to let me anywhere near him again!
So if I ov'd late then I missed the eggy anyway.
The last few days of poas'ing were just too much, I got totally obsessive around 12 dpo (dizziness etc) and actually ended up trying 3 pee sticks in one day! Had to let it go and lick my wounds for a while. Now I'm back on the horse mentally and just waiting for AF to blow the starting whistle! For the symptom spotters among you, all my symptoms ended around 13 dpo, and to be honest I am wondering if I had a chemical pregnancy which wasn't picked up by the pee sticks. I even had serious cramps at 6 dpo which I was convinced was implantation! Followed by the dizziness, throwing up in the morning, and general exhaustion. Then everything just switched off overnight.
Anyways, May babies are awesome! I'm a May baby and therefore a perfect example! 
Biscuits now that you are preggers it is your duty to eat as much cheesecake (and other yummy things) as humanly possible to ensure your baby is being spoiled rotten! The tightening of the waistband is therefore entirely pregnancy-related, and the first evidence of your exceptional parenting skills!
at the bigger boobs!
