I just ordered finasteride, any advice?

[HLTtdc4412]

I just ordered a 30 day supply of finasteride.. I posted a few threads on here asking about thinning and received a cluster of different answers. I know I am thinning though because i am very peculiar about my self and notice things rather quick cosmetically. A little background, I am a 22 year old male with fine hair like my father who is bald now. He started balding i believe around this age . We both have fine hair, but his was curly and mine is rather straight. Mother's side of family has no balding what so ever. About a month ago i started a bulking supplement called Anafuse, this product does not convert anything to DHT supposedly. This is round when i noticed the thinning, so i do not know if they correlate.. I am wondering what are some do's and don'ts, anything else i should use as well.. I have pour a for shampoo and lipogaine 2% shampoo already, but i know they don't do much but make hair thicker. I don't have a lot of money as i am in college and only work summers. I don't want to sit around and ponder what sides i may get, my hair is only going to get worse i need to take action. Things i am wondering: what sides will i most likely experience? What is a good dosage to start at? Am i going to shed a lot? Scale of 1-10 how early do you guys think i caught this thing. Appreciate any feedback.
Sidenote: going to see dermatologist soon, but they are pretty booked so it will be a little bit before i can get to see a MD.I also feel this might be rather aggressive, because I've noticed a drastic change in feeling how much hair i have and how visible my scalp is becoming. Also have not really seen too much hair falling out in shower or brushing my hair. Also checked my bed not much, but my dog sleeps with me so hard determine which from which.
A few pics. Have not been able to see my scalp before this and hair is kind of wet.

My only advice would be to get a hormone panel done before starting it.

I never done one since early this year, which showed my estradiol is quite high. And since I didn't do one before finasteride, I don't have anything to compare with. - maybe I always had little extra estradiol?

Again, I would highly recommend.
