Bleugh is just the perfect word! Cycle #4 here, two very very early CPs during this TTC journey. Starting progesterone this cycle.
Just a bit of encouragement, I was very discouraged when trying for DS a couple years ago because I had a BFN at 8 DPO. I had gotten a faint BFP with DD at 8 DPO, so I thought that's how it would always be, but nope. (And I am an obsessive line spotter--I mean, I look under 5 different lights and take pics from 20 different angles, and tweak contrast and brightness, etc.) There was nothing there at 8 DPO. The faintest ghosty line only came the evening of 9 DPO, and there was nothing that I trusted until 10 DPO. I know people say it over and over but every pregnancy is different, and each baby will implant in a different place, with a different sort of attachment, and a different level of hCG, so there's just so many factors.
I think FF did a study on its charts and came to the conclusion that 11 DPO is the day by which, if any kind of faint line hasn't shown on an early pregnancy test, the chances of PG are lower, so that is my magic day. If I haven't gotten even a tiny hint of a line by then, I know that personally I'm out, but 7 DPO, you're totally still in the game! I think they did another study where they found that 13 DPO was the average day for a positive test, but they didn't take into account when those women started testing (maybe 13 DPO was the first day they tested), what type of test they used, and how closely they were looking for lines. A lot of people still don't know that a very faint line is a positive, so they could easily have discarded their 10-11 DPO tests thinking they were negative.
I dunno, hoping all this info helps a bit!
