When you get pregnant, when do you start experiencing symptoms?

- my period is late by over 2 weeks

- i’ve been very moody

- i’ve thrown up a few times

- certain smells suddenly really bother me

- food i used to love absolutely disgusts me now

- i’ve started craving things i don’t usually want

So it’s been close to 2 months since my last period, and I have had unprotected sex since then. I’m on birth control and my boyfriend pulled out.

Am I making it up and tricking myself into experiencing symptoms or could I actually be pregnant???
