Pregnant? Help?

Wi
So I just turned seventeen in April and the last time I had sex was May 22nd. We didn't used a condom, but he did pull out. I am on the pill form of birth control- however I hadn't been taking it regularly. Is there any chance I could be pregnant? I feel like I've had crazy appetites and cramping with no blood. It could just be stress... But is it too early to take a pregnancy test?? Kinda scared, looking for support, thank you!
