Wive tales

C
I am 20wks 2days. I am not really showing, didn't have morning sickness, don't have cravings but my chin is constantly breaking out with deep under the skin pimples that hurt and itch. Everyone tells me because of all this I'm having a boy only a few say a girl cause my growing acne. Anyone have any knowledge of wives tales?!?
I find out for sure Thursday.
