Birth control

Rissa • Married to the love of my life, TTC #2! We have a beautiful 8 yr old!
Hi ladies! So today I made a huge decision, I went from having an IUD to back on ortho tri-cyclen (spelling) how can I ensure my fiancé that it's still a very effective way to not get pregnant? He now wants to use protection or the "pull out method" to prevent getting pregnant? I only took out my IUD because of the health problems I was having.
