Oh Luv, what an awful bloody limbo land to be in hey???
The only way to really know what's going on is to have the scan as your embryo should be at a certain point by then. In fact, if it's late next week you have it, you should be able to see the yolk sac and fetal pole at the very least if not a heartbeat.
You can do the BT if you want to see how your levels are doing as they should also be at a certain level too just like they should be now. They're not and that's why he's not happy. Now, it could be that you had a late implanter and that's why your levels are lagging behind, but again, you won't know until you have a scan.
I'm one of Wazza's Ladies too and I skipped the last Pregnyl booster for the same reasons you did!!! Don't worry about that, it won't have hurt or harmed anything.
Anyhoo Luv, I'm and sending prayers to the Universe that you've got a late implanter on board and that everything will turn out ok for you
