gobbledigook, don't know what to suggest really. I took pill years ago & felt similar to your description , despite trying several. I have also tried mirena, felt ok on it, but once it was removed, felt so much more 'normal' (libido, emotianally etc) & ditto for mini pill, so I really feel that any hormone thing is going to have this affect on you to some degree or other, this is my experience anyway. I'm currently ttc no. 4, so just stopped taking mini pill & feel so much better, tho at time didn't realise the affect it was having on me - subtle.
re persona, I think it's great, but in the long run, expensive. Puls you can't use it for, I think 3 months from either birth, or b/feeding, if you are, so that's potentially a whole year (was for me, so although I enjoyed using it, couldn't use it again once sprogged up).
There's a more modern methed, to the Billings method, that's supposed to be like 99% effective. You can do a course, a bit like ww and you get a tutor & they teach you & monitor your learning progress & give loads of support.it's supposed to be easy enough once you've learnt & I think it has the advantage of still being as reliable even if you're b'feeding/irregualar cycles/premenopausal etc. Obviously not as convienient as popping a pill, but at least if you do a propper course with traing it's gonna be a lot safer than reading a book & hoping for the best.
I'll see if I still have the info if you like, let me know. tough one isn't it? God knows what I'll do after no. 4, because that really is as much as I could take I reckon!
btw, have you actually had no 3 yet? congrats either way 9be it on pg or birth
