Ladies! Has this ever happened to you?

I’m really sorry if this isn’t the right group, i’m just not sure where exactly to ask this lol. well my period is now 16 days late and i’ve just accepted that i’ve missed this one. i would theoretically be just about 5 weeks along if i am pregnant. my periods are never this late and i haven’t been stressed at all and nothing about my weight or diet has changed. the home pregnancy tests are still coming back negative and where i’m at in my life, i can’t get into the doctor quite yet. i read on google (super reliable, i know lol) that it’s uncommon but definitely not unheard of to not get a positive home pregnancy test result until later in the pregnancy. i’m just wondering if this has happened to you or someone you know maybe?
