Help!!

So I got lost with where I was on my pill I forgot to take them a few days here and there and I’ve been all over the place using different packets depending on where I am. I’ve stopped the pill to have my period but the only thing that is there is brown blood.. and I’m freaking out that it’s implantation bleeding seen as I’ve stopped my pill for about 2/3 days now and no sign of red blood, just all brown.. I’m terrified can anyone help?!
