If you want to know more about feminizing HRT and how it affects the body, 'A Practical Guide to Feminizing HRT' and 'Transfeminine Science' are both really good resources IMO:
The futile attempt at answering every possible question for someone looking to trans their sex.
Transfeminine Science is a site for information on hormone therapy for transfeminine people.
And for more info on how to do injections, Planned Parenthood Greater Texas has great videos available in both English and Spanish showing just how to do them:
