Hey everyone, I’m really confused right now...so 2 and a bit weeks ago I had my period.

On the underlined dates I had unprotected sex with my partner (we are trying for a baby)

But today and yesterday I’ve been having like brown/black thick muck looking stuff in my pad (sorry for tmi) but it doesn’t look like my normal period...

I’ve been having tender boobs and I had a mild cramp 1 day before I saw the browny/black looking muck

Could this be implantation bleeding?
