Firstly thank you all for replying; I really appreciate your help.

Thank you for sharing your experience and hindsight. I'm only just learning about this but the gel option does sound attractive.

Thank you for all those links - I will start going through them - I need as much info as I can get right now.
I am going to the doctors in about a fortnight but I'm a little alarmed at your suggestion to get this resolved before it gets worse - I hope if it does get worse the gel or tables could still help and I'm not taking some sort of risk by waiting 😕.

Thank you too. That was a question I'd not even thought of and is a really good point. I used to have a pretty regular 26 day cycle but the months prior to the coil were all over the place 26, 40, 30, 26, 40, 17, 28, 31, 29, and 17 again - those 17s and 40s were really unusual for me.
At the moment I'm leaning towards this being the menopause rather than an odd side effect of the coil. I'm a bit shocked 🙂
