Indent? CP? Positive?

It looked more pink than colorless in real life but I know FRER are notorious for indents.. last night I took one and I had the faintest squinter (my husband couldn’t see it) so I was happy when I saw this line this morning but not sure…. I went on to take another few tests a few hours later (after drinking a lot of water - like 40 oz haha) which came out as negative as well as negative digital…. Feeling out…? Was the first one just a fluke/indent or a fake positive? I’m around 12-13DPO and period is due today. With my past pregnancy at this point I had a very dark positive… feeling bummed. Thank you!
