Freaking out!!!! Help !

I’m 20 and I’m extremely scared about being pregnant. I’ve been on birth control for almost 3 years, never miss a pill or take it extremely late. My period was due June 4th and I got it but my nerves have been so bad and my anxiety and my period was short, heavy at times and light at other times and lasted around 4-5 ish days. I also never let my boyfriend finish in me even though I am on birth control. I’ve taken multiple tests... digital, red dye and blue dye... the only one that appeared to say pregnant was the blue dye equate one. I am 27 dpo. The digital one said not pregnant twice, and the red dye ones seemed to have no line. I’ve been having bad headaches, my boobs are veiny, and my stomachs been weird but I can’t tell if it’s my anxiety or if there’s still a chance I’m pregnant. Any advice ??
