The sides you're experiencing are classic virilization signs. Body hair, acne, and voice deepening. The voice is the most serious one because once it changes it can be permanent. Stop both compounds now. Not taper, just stop. 25mg of each is way too much for a female, Anavar should be 5-10mg max and Winstrol is one of the harshest compounds for women when it comes to virilization.
If you want to run something in the future, Anavar solo at 5mg per day is the right starting point.
