16 and possibly pregnant??

Okay so im on bc and am usually pretty good about it.. but at the beginning of the month i missed 2 pills. A week later (dec 10) me and my bf had sex 3 times, 2 of which were by “pull out” the last few days ive been spotting and had a few cramps when i shudnt even start for 2 more days. Im really scared that this might be implanting and its too early to take a test. I just feel so alone bc i cant talk to anyone about it because i dont want to scare my bf.

Could i be pregnant? I know you hear it all the time but im almost positive that i am. HELP?!?!
