Late period...seriously!

Shelby
I must have been stressing lately because here we are with no period still...I have struggled since I was sixteen when I started my period to be regulated. Once I started birth control it kinda regulated to every month but I ended up not taking them anymore because of the horrible side effects. After I stopped taking them my periods started to regulate and over the past year they have been on the dot every thirty days like clockwork. Last month it was a few days late and now this month on day three past it I do not get it. I am not pregnant already checked I seriously kinda wish I was though but I guess if I am stressed too much then of course it will be harder to conceive. I do not like being stuck in this hard time because not only have I not used any form of birth control for awhile now I thought there was hope at the fact that my cycle was consistent because it made me feel that my body was doing as it should as a woman. Am I overwhelming my thoughts maybe and that is the problem?
