Back story: I went for an IUI 12 days ago, my progesterone 7 days after the IUI was excellent. I have my blood test scheduled in 2 days. I thought just for the fun of it, let me take a pregnancy test. I wanted to have "that moment", you know? I've been trying for 2 years, and I've become so used to seeing a negative result. So, I took a test on 11 DPO and at first saw nothing, but then a faint line began to show. I assumed it was an evap line but as time passed it started getting bluer in color. I read that blue test can be inaccurate. I took another test this morning first thing and the same thing happened, except this line is a little darker (both test are from the same store brand 2 pack). This morning I decided to go to the store and buy a FRER pink dye test, and I got a negative result. No line at all. I'm saving the digital test for 13 DPO.
