Help!

So a few weeks ago I came off of my birth control pill. I had a little bit of bleeding (possibly just breakthrough bleeding) right after coming off. Well 3 days ago, I was supposed to start my period. I wiped and saw a tiny bit of very light blood so I thought I was starting. Well all the bleeding stopped and I haven't had my period yet and I'm like 2 or 3 days late. I haven't had any pregnancy symptoms except one day I was cramping bad because I had to use the bathroom.. I wanna know if this could be an irregular period from coming off the pill or could I be pregnant with no symptoms??
