Spotting off bc

So ever since Ive gotten off bc i have been having random spotting. Some look like implantation some would last for a couple hours and wont see anything for days! I did have my withdrawal and still waiting for my period. But all ive been getting is spotting. I feel pregnant but i get negatives i dont have a doctors appointment till April. I just want to know im not alone! Any one else have had this experience. Im dying here!!
