Any ideas??

I’m 6 days late. Had 1 faint positive test 5 days ago in a frer. I’ve been taking clinical guard tests since and feel like they are all super negative. I had spotting from 12 dpo (2 days before missed period) all the way until 3 days late. When I say spotting I mean bleeding in between cycles. It was never enough to fill a light tampon( never came close) and only enough to show up on a panty liner. Today however I checked my cm and it’s very creamy like lotion and there’s quite a bit of it. Could I be pregnant and it just not show up on the cheap tests? I have an appointment at my doctors office next Friday for a pregnancy test and ultrasound to see if there’s a baby in my uterus or not. Has anyone had similar issues and ended up actually pregnant? I’m freaking myself out over here because we really want a baby and have been trying for almost 2 years and this month I really felt pregnant.

Side note— the spotting was dark brown/red the first day at 12 dpo thought it was implantation bleeding because it was very stretchy

Then the next few days the spotting was like a orange ish color also very stretchy

Then the day after that it was very light brown and stretchy as well.
