Implantation bleeding

lanae

So my last period was nov 9-12, I didn’t have a period until dec 30 I threw up a few days before that but my period was different it was brown blood the whole time and it was light not like a normal period and it stopped on the 1st I had some brownish pinkish spotting a day or 2 afterwards which I never experienced. Could that have been Implantation bleeding?
