I could use some insights as to what’s going on with me !

Hi all.

So I had a miscarriage in April, and since then I’ve had one regular period. Afterwards, we’ve been trying to conceive. Well, I am suppose to get my period 5 days ago but still hasn’t happened yet, but those cheap pregnancy tests off amazon always coming up negative.

yesterday night i had some pink spotting in my tp after urinating, and had some light cramps , (basically felt like how my periods start ) except there’s been no blood since.

what’s goin on with me? could that be implantation bleeding, or just an irregular period due to the mc?

could use any opinions cause i’ve never experienced this before
