What should I do?

Alana • 17 year old junior from West Virginia!☺️
So me and my boyfriend had sex on October 17th when my fertile percent was on 11 or something I'm not sure and I was supposed to get my period on November 5th and I took 3 test 2 were negative and one was broken I have had a lot of pregnancy symptoms! Like pants not fitting, tired I have woke up a couple of days trying not to puke and then it continues on and off through the day, very moody, and bad heart burn and just light cramps. What should I do, both me and my boyfriend are 16
