Implantation bleeding ??

Melanie • TTC our rainbow baby 🌈💛 one angel baby in heaven 😇

I had a miscarriage December 5th . I haven’t had a period since then & we’ve just been having sex I haven’t been charting , doing opks or anything because I don’t know when I’ll have my period & idk if I’ll ovulate . Last night I wiped & I had very light light pink discharge? So I put on a pad because I thought maybe I was about to start my period & then today around noon there was a little on my pad but not a lot . I took off my pad & hadn’t bled since . Is this implantation bleeding or what?? I’m always irregular if that helps?
