Pregnancy? 16 years old?

Ok so about a month ago I had sex and the condom broke. It didn’t break inside me and we caught it right away. Of course me freaking out, I took a plan b. A week later it broke again this time inside me and I felt it. (Neither time did he cum) Again I took another plan b (don’t do that it’s dangerous) so my question now, Is there a chance I’m pregnant because I haven’t gotten my period in 4 days. But then again could i be late because I pumped my body with a ton of hormones? Anything helps. Thank you!
