Did anyone actually mistake IB for AF?

Moo

Hi all, last week I had weird discharge on the day my period was due. I took a test and saw a tiny tiny line, chalked it up to an indent. I took another test the next day because AF didn't show up, and I got this:

(Yes, this was within the time frame and no, not a watermark. I took the test apart and the line was pink but that was done after the time frame :) )

I take a test the next day because AF still doesn't show; and I don't see anything. So I convince myself it's an indent, again.

(TMI warning) I got my period the next day (4 days late) and it was weird. It was watery, lighter, and more of a muted red (like a dull crimson) compared to my normal dark but bold cranberry red. No clots either. It lasted two days, and while it was lighter I still wore a pad and changed it occasionally for cleanliness sake.

The 3rd day I had light pink and brown spotting. I had some more spotting on day 4, and now on day 7, I still have some watery brown spotting (not normal for me).

I am on vacation for Thanksgiving so I don't have access to tests. I did learn in school it's possible for some women to bleed red when having IB and spot the first few weeks, but I didn't learn exactly what it looks like. I'm wondering if anyone had IB that they mistakenly thought was AF and later found out they were carrying??

Here is what my bleeding looked like. This is how light it was day 1 and 2 when I wiped (usually the paper would be soaked).
