This is my favorite thread so far. I don't like to think of myself as "crazy", I like to think about it as eager. lol
Here is my list:
When you stop using your OPKs after you O and the next day start using HPTs.
When your husband is showing you a chart for the stock market and you are seeing the O, implantation, pregnancy indicators.
When your DH asks for sex and the first thing you think of is that it is nowwhere near your O time.
When you have the pricing and picutures for the nursary furnishings and you are only 5 DPO.
When you search the internet to look at other peoples HPTs to see what they are getting at this early stage.
