I’m late...

so nobody knows that me and my boyfriend have had sex, and with a six year age gap and my parents not yet knowing about him, this is a big deal. i waited to have sex for a while after i actually wanted to out of an intense fear of pregnancy. well now my period is late and i’m terrified to tell him and even though my period is typically not on time i am worried this is too much time that has passed for me to not be concerned, especially being that i am no longer a virgin and pregnancy is a risk now. we’ve been using condoms, they’ve always been bought recently as we buy the small packs, and he always changes and wipes himself off after he finishes or even if he hasn’t and just has to pull out for a while for any reason. they’ve also never been stored in the bathroom so they haven’t been exposed to anything that might damage them. i feel as though we have been pretty responsible but i have such an intense fear of pregnancy, i don’t even want to take a test for fear it will come back positive. at least this way i can still hold onto hope that my period will come. i haven’t experienced any telltale signs of pregnancy aside from the late period but i have experienced symptoms typical of my period. can anyone provide any advice or comfort? i’m really freaking out here. how long can i wait before i need to test?
