I'm shook

I had a dream while I was napping that was about some cards or whatever. There were two people plus me making it 3 and there were these cards which we got a present when something happened like getting pregnant or getting your period. There was a present for each person when they accomplished something basically. There was a card that I could open when I got my period. I looked on the back of the card and it said "3 days". And this was a lucid dream and I just thought it was a random number that was something made up. Well just a couple minutes ago I looked on glow and it said my period was in 3 days. I'm not sure if this is a coincidence or not because I didn't check when my period was due in a week or two. What do you guys think?
