This can’t be.... maybe trigger for some

Er

So my period was 4 days late all negative tests even on Sunday ...started spotting last Sunday and assumed it was AF. My period never fully came on. I would put a tampon in and the tip would have a little bit on t like every 12-14 hours. Color varied from bright red to pink to brown. All week off and on. Like I said I would go 12 hour with no blood at all even at night time. I assumed it was a very light weird period but whatever. I haven’t had any bleeding in 24 hours but my breasts have been aching...for shits and giggles I took a test tonight. There is a line 😳 I could not for the life of me get it to show up on my pictures as well as I can actually see it in person...I’m scared shitless because if it is a real line I’m worried I miscarried because that’s what happened the last time I had a MC...didn’t know I was pregnant starting bleeding and then got a positive test only to lose the baby a week later. I have 1 test left...do I test tomorrow morning or wait 2 days? Any advice is welcome.
