To Cloth Or Not To Cloth?

Taryn • Married to the most amazing man in the world! :) Trying to conceive our first baby. His 3rd & my 1st - Currently on Clomid 50mg - PCOS affects my fertility - Liberty University- Ultra Conservative Right Wing Republican- Trump Train
So ladies I am currently undergoing fertility treatments and ttc. While doing all this I've been thinking about diapers and formula, trying to get my own opinions going.
I know nothing about Cloth diapers. I don't know where to find them. I don't know how they work. I need the run down. 
Do you still pin them on?
Are there alternatives to pinning them on?
Is the diaper rash worse or about the same as with disposable?
How bad do they leak? 
Are the blow outs as bad as with disposable?
Do you put any kind of liners inside?
Are there any outer covering for them to prevent leaks when out?
Are they different sizes or one generic size?
How many of each size (if they are different) do I need?
Any advice or pros and cons you can give will be greatly appreciated!!!
