Ok so this is our second baby and I've been on 2 birth controls before and didnt like either.... what are your opinions ladies?

When I got married I was on the depo shot for almost 2 years and seriously made me moody and I gained like 30 lbs and constantly felt sea sick. I stopped taking it and quickly got pregnant with our first. When he was born I got the Mirena IUD but started having weird phantom pregnancy symptoms and feeling sick again. I got it taken out and almost immeadiately got pregnant with our second... apparently I'm super fertile or something and I dont want to get pregnant with a third any time soon!! (Some day, yes) I'm concerned about forgetting the pill daily. I was thinking maybe Paraguard?
