Implantation bleeding?

Hey ladies!

I have been ttc for the last few months and last night I noticed some light bleeding, so I thought it was just my period coming super early.. (I’m not supposed to start until the 4th) this morning I go to take the tampon out and it was barely anything with brown blood.. sorry.. tmi.. could this possibly be implantation bleeding?? I’m slightly crampy, not enough to grab the midol. I’m also super irritable and my breasts are tender. I feel like I’m over thinking it.. like I do every month. I’m just wondering if anyone has had implantation bleeding? And if that sounds like my symptoms.

Thanks y’all!
