May be pregnant 😁😁😁

So my period usually starts like clockwork. Well I was supposed to start last Saturday, but I didn’t. So I was like ok that’s fine maybe it’ll start tomorrow. Well here it is five days later and still nothing. But some interesting things have been coming up instead. For about two weeks now my nipples have been hurting. My bras aren’t fitting right either. I’ve been more tired as of late and whenever I drink sugary drinks I’ve felt nauseous. So I’m asking you ladies, is it possible I’m pregnant?
