Is there an alternative for minoxidil for women genetic hair loss? (Photo)

Hello, I have very thin hair and i tried alot of treatments but on my last visit to a derma doctor he told me that this is a genetic hair loss case and recommended minoxidil as a treatment. My question is, is there an alternative or another way to help in my case ? Im getting married soon and im worried about the fact that it affects in pregnancy and that i have to use the minoxidil spray forever . Thank you
