Late period

So.....my period is late one day and I’m stressing out...the only reason I am is because I’ve had dreams several times this month that I’m pregnant and I give birth to a child and it gets even more freaky when all of my in laws and my mother have been talking about us having kids and the possibility of me being pregnant and it scared the living shit out of me....I’m not even 18 yet....I don’t want a kid are you joking?!?! I don’t have the Financial stability to care for a kid!!!! Ugh help.... (we’ve already taken two pregnancy tests both turned out negative) What do I do?
