So disheartened update at bottom

So I am 13 dpo today. Supposed to get AF tomorrow. I started testing with the dollar tree pink cassette tests at 8dpo and got a super faint line, I got so excited and took a couple dollar general 1 dollar tests and they had a super faint line also so of course I had to get an frer and there was a super faint line on it also, so faint I couldn't get it to show on pics but was definitely there. Not wanting to spend alot of money on tests I decided to go back and get more of the dollar tree pink cassette tests and have tested every day since then and all of them have had lines but are still super faint and not getting darker at all. I have even spent more money on frer and they are still super faint and not getting any darker. Also the pink cassette tests I took today were even fainter than they have been (almost non existent? so I guess I am having another chemical. I was so hoping after 3 years, 1 miscarriage and a couple of possible chemical pregnancies that this was It but I guess not. Ugh. I want to cry so hard.

So AF just showed so I guess it's on to next cycle.
