Shorty - if I may give you some advice? If you will be getting a blood test, try waiting instead of HPT-ing early. Feel positive and don't stress yourself, give your embies the perfect stress-free environment so they can nestle in. The blood test will come early enough and HPT-ing might just stress you, worry you - keep your Mummy-Karma up until they do the blood work (which ought to give you your answer earlier than most HPT-s are able to give you a positive, because the hormone is found in the blood earlier than it is in urine).
But that was just my way of thinking - if I had a negative HPT before the blood test, I would be worrying and worrying... if I started seeing lines, and the blood test is negative, I would be heartbroken and would find it much harder to deal with. That is why - for me - I decided against the POAS (although I was oh so tempted) and waited for the blood test.
In the end, it is up to you and what you feel is easier to deal with
I believe that with a 10.000 trigger, it takes about 10 days to leave the system.
Whatever you decide to do : CONGRATULATIONS on being PUPO
and lots of Mummy-Karma
to you
