What birth control to use?!

Hi beautiful ladies! I need your help!

I'm 44 years old and have my IUD Copper that I'm about to get removed but now I don't know what to use!

The rhythm method and condoms I guess. 🤷🏻‍♀️

My husband and I are still deciding if we would like to have a baby, which I'm scared 😳 about the whole thing cause our age; he's 53 years old. I have from previous marriage a Son 20 and Daughter 18 years old. My husband has no kids!

Thank you all for your time! ☺️
