Hair growth during pregnancy

Hi girls I’m a first time mom, I had to have all of my hair cut off in January (not all the way off but it was a very very short pixie), it is slowly growing back now and is at a sort of spiked sticky outty length, very much still a pixie cut but it’s getting longer. I’m about 8 weeks and I’ve heard that during pregnancy your hair grows like crazy? Is that true?! If so double blessing, beautiful baba and hair growth!! Lol let me know, I’m hoping it’s not an old wives tale!
