My husband refuses to use condoms as a contraceptive saying it kills the spontaneity of the moment. I do not want to take any oral contraceptives as they have side effects. Are there any other options I have?

if you're not planning to have any more babies, why don't you ask him to get sterilized? it's a very simple procedure and will ensure you don't get pregnant. i wouldn't recommend the hormonal injections as they come with some long-term and lifelong hormonal issues.
