Great to hear about the second positive test!!
I agree that you should take those with you to the Dr's & tell them you don't need to do another test as your UTD you just need your BT done now. Dont take no for an answer this time.
I dont understand your Dr getting you to do another PT when you've already told him you got a positive HPT. Does he not believe you can tell the difference between one & two lines on your test at home?? My doctors have always just taken my word for it & done the BT straight up.
Try to see a different doc....
