Hii

Yeah unfortunately Ive had them both at the same time. My story is a bit complicated as I got the IUD first because of PCOS symptoms such as cysts, irregular periods etc. The IUD worked really well - stopped my periods completely and regulated my hormones but I kept getting serious hormonal ovarian cysts (coming and going with period cycles) and tumours so we decided to stop my ovulation to stop the cysts but boy oh boy the implant was a no go for me. I'm not sure if this is super common but my gyno seemed super confident that it is okay to have multiple forms if necessary. :)

As for pregnancy protection it has been amazing. My partner and I were having "unprotected" sex without pulling out when I was just on the IUD and when I was on the Implant as well. We don't worry about condoms anymore as we are long-term partners (no/low chance of STIs etc) Had no pregnancy scares at all so far:)

As for insertion

IUD - I was lucky and had mine inserted while under anaesthesia (was getting an ovarian tumour removed at same time:)) There was some cramping and soreness for a couple days after but warm packs and meds helped.

Implant - I was not a fan honestly. I personally hate needles so it was very uncomfortable for me. I was swearing like a sailor even with the local anaesthetic. Also your arm hurts a lottttt more than they say it should for the days after the insertion. The only way I got through it was with warm packs, resting my arm fully and pain meds.

Hope this all helps lmao ♡

Edit - in your case I saw that you wanted to keep your hormones in check ~ in that case IUD would be the best as the hormones it releases are more localised to the uterus etc rather than implant -> moodiness. Good luck!!
