Does copper coil (IUD) cause migraines?

I wanted a long-term non-hormonal option and this works great. My first period after having it put in was a lot heavier than usual but it settled quickly back to pre-coil levels. I had concerns that using the copper coil with endometriosis might not be compatible. I do get more painful cramping during periods and around ovulation than pre-coil but it's still very manageable. Overall for me it's been by far the best of a bad bunch!

My insertion was surprisingly a good experience, great communication, pain relief and local anaesthetic provided as standard. I didn't have any concerns during the insertion, however I experienced cervical shock about 15mins after ... not nice but supported very well by the team. Since then I have had inital breakthrough bleeding, lower back pain and cramps for about a week after the appt. My first period since was heavier and lasted 6days instead of my standard 4 days, I was also early by 3 days. Apart from that some spottinghas remained. I suffer with migraines and saw an increase in the amount from the insertion, since then its gone back to normal. Overall I am excited to see how it goes, hormonal contraception doesn't agree with me so not an option.

Pros - none hormonal, the placement doesn’t cause me discomfort, I can forget about it & for 3 years hasn’t caused me any concern on unwanted pregnancies. Cons - the doctor I had to insert the coil was amazing, and it was no more discomfort than a smear, however the 2-3 days following I was in a lot of pain. It did settle. I suffered with BV 2/3 times whilst my body became used to the coil in my body. Vaginal dryness is the biggest thing for me which I’ve never exp before and lastly longer heavier periods. The heavy side has taken 2 years to settle down, the random cramps and spotting has settled and less frequent and my period lasts longer. Not completely ideal for me but currently the pros of protection and being non hormonal it’s the best option for me.
