Since being with DP I have had several issues with my mirena coil when I had previously had a blissful 5 years of period and baby free awesomeness with it.
My new coil (the one I had fitted after getting together with DP) managed to 'migrate', causing me extreme pain and necessitating a removal of said coil and a very painful re-insertion of a new one. I have no medical confirmation of this but I strongly suspect that this is due to the fact that DP is *ahem rather well endowed and quite 'energetic' during sex, especially since I am now, only 3 months on, experiencing the very same kind of pain as before when my coil migrated 
So it would seem that maybe the coil isn't suitable for DP and I due to previously mentioned issues. But what is my alternative?
Neither of us want a baby.
I don't want to take the pill (previous migraine issues).
I don't want the copper coil (probably will have the same issue/I have heavy periods).
We can't use condoms (DP genuinely can only use special order condoms off the internet that are EXTREMELY expensive. We did it for 3 months in between coils and was a real downer on our sex life).
Dp won't get the snip (nor would I ask him to) and sterilisation for me would mean a) a rather invasive op and b) I would still have periods for the next 20+ years.
I hate the idea of the implant and I worry about the injection giving me the same migraine issues as the pill.
Help!!!!
Aibu in thinking that the coil issues are down to DP? Aibu to not know what to do to avoid periods/babies without DP getting the snip? Arrrrrg!
