Yeah a line IS a line - what brand of test are you using? I swear by Discover One Step's - they are the best in my opinion!!

I got my first bfp with that brand when I was only 10 or 11 dpo - line was faint but definitely there!

If you are getting lines and have been for days then it is a really good sign.

I would call your doctor tomorrow and make an appointment to get a referral done for your blood test and put yourself out of your misery hehe

Bloodwork does not lie so at least you will know for sure!!
