with Kat, I had a BFP HPT at 21DPO and a BT that day confirmed it (was on honeymoon in Perth and a PITA to find a Dr who'd take on a client for one day type thing *L*). With Jess I was over a week late for AF But having just given birth two and a bit months before I wasn't toooo worried even tho I felt pg. I started with the M/S (afternoon sickness for me) and went for BT as all my HPT's were coming back -ve and I knew I was pg! Anyway, I got a BFP BT and still took another 4-5wks to get a BFP HPT (wanted one for my baby book).

I agree, it depends on ur Dr. Even is u get a BFN HPT at the drs, you can still demand a BT. I did that a few weeks ago when Af was a wk late and I had NFI why. I have developed a cyst on one ovary so at least I knew why. But nothing would have been done had I not asked for bloods and an U/S to try to find out what was going on!

Goodluck and I hope you get that BFP!
