What did use in between DS1 an DS2? Was that workable?
We didn't. Because of my birth injury, we weren't able to have sex for 6 months, and there were still complications, etc ... when we got the all clear, we started TTC again, and got pregnant in 2 cycles.

Mirena is the ring, yes? How do you find it?

If you are very careful about taking it everynight its fine.
That's the issue for me ... I work very long hours sometimes and so am not great at taking it at a consistent time ...

Ring you can do yourself but I found it uncomfortable I did have a mid prolapse at the time. Mini pill left me spotting constantly
Mirena? Diaphragm? Could you try a depot injection? I think it's every three months so if it doesn't suit you it's not as long as the Mirena or implanonon, although I guess those two can be removed if it gives you nasty side effects. Good luck
Gah, So much to think about ...

Maybe I should just not have sex until DS2 stops bf and then I'll go back onto my old pill ... ?
