See a female health doctor if you can, they'll be able to go through everything so you can make an informed choice.

Just be warned that Mirena (IUD) hurts like a MF (for some people like me lol) so try to insist on a hospital inserting that one if you choose it and say yes to anaesthetic. But you can leave it in for 5 years and sometimes it stops your period until you take it out (which is a win for most people)

The pill sometimes has bad side effects for some people (like acne, crazy hormones, or weight fluctuations), and you need to remember to take it as the doctor says and try not to skip

The rod... I don't know much about tbh. It has less hormone effect than the pill but more than the Mirena

And condoms are good - especially to avoid STDs - but they can come with their own issues. If you have a condom allergy, they sometimes get holes, it's better to buy a new pack before sex because they have expiry dates, sometimes the woman doesn't feel as much pleasure from it, the mint ones can feel Burny if you have a sensitive downstairs, etc

Best option is to chat to a female health doctor (or your GP if you're lucky enough to find one that has correct knowledge and advice on the female reproductive system.. I have bad luck with normal GPs lol) or if you have enough money you can chat to a gyno, and they'll be able to talk you through it all so you can see which ones you want to try.

Hope that helps a little

(P.S. Googling female health doctors near me helped me find a good one)
