is it my period?

So i was supposed to get my period 5 days ago. The first 3 days i got cramps but no period. i also broke out which is what usually happens, but i also didn’t bloat like i usually do. I also feel like i became more irritated, and horny lol. Which is typically what happens on my periods so I kinda got everything except the bleeding. and now I just woke up for school and started trying ready, and I wiped and there was like blood kind of but it was barely there. But i mean nothing else has come out i mean it’s only been like 30 mins since then but i don’t know. I’ve never had sex before btw, and I was on birth control for a whole month but i stopped 3 weeks ago, which is why i’m expecting my period now. But who knows. Any ideas??
