I NEED HELP ASAPP ROCKY

So I’m on birth control and I have a tendency to have irregular periods but not recently, I’ve been cramping for a few days but I’m 9 days late off my period( usually I am a week off than normal since I’m irregular) I had unprotected sex on the 15th but he didn’t cum in me, I know he didn’t because he pulled out and I finished him after. I take my birth control regularly and accurately. Is there a chance I could be pregnant? I haven’t had any symptoms, I’m just wondering if I should get it checked out or if it’s normal for other people too. I also just started birth control around 3-4 months ago and I heard your body can be irregular and it takes time to even out but I’ve have my period every month every since I started it.

Any help or advice is greatly appreciated ❤️
