Changing pubic hair colour?!?

Robyn

So I decided to brave the shave after about 6 weeks and although I had to do it by feel, I noticed that my pubic hair (that’s usually black) has become lighter, almost auburn and some hairs are even blonde! Has anyone else experienced this? Does this mean my baby is going to have light hair (both my husband and I have dark hair and olive skin)? Or is just hormones?
