nervous about BF

Laura • Wife & Mother of two❤
I'm hoping I'm pregnant. I find out tomorrow by a blood test. (Fingers crossed I am). anyways, with my 1st child I didn't breastfeed. I was too scared I was 19. So I just bottle fed. I wanna know is it hard to BF? I'm thinking about doing it with my other children in the future. what are the pros and cons of BF? I just wanna start writing things down and talk to my husband about it. 
Thank you in advance:)
