Can implantation bleeding have stringy bits in it? I know it doesn’t have clots in it but these bits don’t quite seem like clots.

I had a one bit of light pink spotting 2 days ago, then nothing, then a bit more pink spotting today that has become very slightly heavier but had a few stingy bits in it.

I’m not due on my period for another couple of days. The light pink one off spotting the other day gave me high hopes but now I think it’s probably my period 😔
