TTC/ no period/ negative test result?

Okay so a little back story I was on birth control for about a year before we started ttc. Well, it wasn’t really ttc- if it happened it happened (I never tracked my period I knew it was at the begging of the month and therefore never tracked my ovulation or even know if I’m ovulating). After about two months of being off bc my periods regulated. Fast forward we are now ten months from my regular periods. I have missed my two most recent periods. I think the first missed period may be because of stress or something else idk. Bfn all month after - however I wasn’t testing in the morning all my tests were at night. When the time comes for my second period missed period.. well I missed it. (This week I was supposed to have it.)🤣. At this point it’s consuming my life I’m researching pregnancy at every open chance. Two days ago I tested in the early morning with blue dye and a very very faint second line was there, again the next day with blue dye the same thing. Well you guys told me it’s better to use pink dye. So yesterday I went and got three pack first response tests. I used the first one and it came back negative, could I have drank too much water before or my hormone levels were too low because it was at night? So I wake up this morning and take the first response digital. I rip open the bag to test and the little clock was blinking with a question Mark- didn’t seem normal to me. So I waited and waited but it came negative. I couldn’t forget about those two faint lines I saw so I read the instructions, the digital test was old, or broken, or default. and now I have to wait until the morning!! I just wanna know what you guys think, I don’t really have anyone to talk to about this. 💜
