Pre seed

Lauren • Got my rainbow on September 26th. 🌈👶🏼 👼👼👼
Is pre seed for women who don't produce egg white cervical mucus? My cm is always super white. And I've read that's not healthy for sperm to survive. Anyone alike that used pre seed an had any luck? I've been ttc for a few years now and I've had 2 miscarriages.
