Hi Ruth,

First all, congratulations on getting faint bfp's with your home tests.

Usually blood tests to confirm you are actually pregnant should only take a couple of days to come back from the lab. I know mine did anyway. I had my blood drawn on the thursday and went to the doctor on monday and he had the results.Some doctors if you request it and if they allow it - can put it through quicker than that and you can have the results back the next day but yeah depends on your doctor and your circumstances.

In my opinion (because you say your lines are faint) if you know where you are at in your cycle I would wait until you are close to being due for your AF or even overdue before having a blood test done, that way your body has enough time to build your HCG levels and you will get a better result.

Good luck with it and I do hope that this is it for you!
