Positive Test 2 Days After Period

Alright I need to know if anyone has ever experienced this, and if so, they went on to have a healthy pregnancy.

After my 1/25/24 cycle I ovulated on 2/6/24. Experienced what I thought was implantation a few days later, and then breast tenderness set in. I assumed this wasn’t our month, because my period came 2/18-2/22, but the breast pain lingered (usually goes away a few days into period). I took an HCG and LH est on 2/23 for the heck of it because of this. HCG came back as a faint positive, and LH came back super bright (looked like what it looks like on days 11-13 of cycle when I typically ovulate) Thing is, boob pain went away. I don’t have any other symptoms that would lead me to believe I’m pregnant. I’ve been noticing some smells are gross, but idk if I’m just in my head.

I’ve taken tests the last few days, and though they aren’t getting any darker, a second line is definitely there (dye, not just an indent line). Digital tests still aren’t picking it up though.

I’m trying to stay optimistic but part of me assumes this is a chemical pregnancy.

I unfortunately had a miscarriage back in December and it followed this pattern as well. Is it possible to have a healthy pregnancy, or should I just accept loss now?
