after you ovulate your progesterone levels increase, this leads to symptoms such as sore boobs, bloating etc
Non-pg hCG levels are usually less than 2 (some labs say less than 5) and should double every 48-72 hours after embryonic implantation. If an embryo implants at 7dpo and doubles every 48 hours, assuming anhCG level of 2-4 just before implantation, it would only be around 8-16 at 11dpo. The lowest official level that most hpts will detect is 20. Some say they go as low as 10 but I don't think that's often or consistent. I have seen some examples of 10 and 25's lined up next to each other and and the 25's were showing sooner and darker than the 10's.
Then you have to consider that implantation may occur later. The hCG may not rise that quickly. The urine may not be concentrated enough. Your metabolism may keep hCG from getting into your urine as quickly as average. There are so many factors that can affect the earliest any one person and any one pg will get a BFP that a negative is not definitive until the witch shows.
Thank you so much for your replies - I have managed to hold off and not test at all. Im definitely going to wait till the end of this week when I am due my period. I just wish it would happen already - but dont we all. Thanks for listening ladies, its really comforting to know that there are others in the same boat.
Best wishes to you all xxx
