Nicrach try to get a blood test tomorrow so you dont have to wait over the weekend for the results. It depends where you are but some labs can have the results in 4 hours (this is for a qualitive blood test) otherwise the next day is usual. Some will even phone the results but not all and it's not always that great especially if you have questions as the receptionist cant answer them.
I find that hpts dont work for me either, i'm going for my second bt tomorrow as my first was -tv. Day 42 for me unusual as i am regular 30dayer! I have my fingers crossed for your BFP - keep us posted
