How did you know you were having a boy ?

I think I’m having a boy because I’ve gotten pregnant 3 times before my current pregnancy and I’ve never had

- pupps

- acne

- changing of deodorant

& last but not least STINK VERY STRONG SMELLING PEE !

The point is now I do , I’m currently 13 weeks pregnant my other 3 pregnancy’s I terminated lasted up to 12 weeks I’ve never had symptoms like this ...

So my question is , what were clues to know you was having a boy at the time of your pregnancy?
