Hair loss

So i got a super weird question for u ladies lol. So with my first pregnancyafter i gave birth i developed alopecia because mt hair loss was so bad! Had to go to a specialist to get hair growth injections. Now im 20 weeks pregnant and today i noticed a few times when i wiped i had pubic hair on the toilet paper! Is that normal has anyone lost pubic hair during pregnancy!? I havea doctors appointment in two weeks so going to have them check into that but thought id see if anyone noticed this oddness lol
