History of breakthrough bleeding on contraception, what to try now?

[Chocoholism]

I've tried Yasmin, microgynon, cilest, Evra patch, depo provera injection and mirena coil. All gave me spotting most days even after trying for months.
This was a few years back and before I had my child.
Anyone else with similar experience and can suggest something I could try?

Here's an AIBU thread which might be helpful

Have you had the spotting checked out BTW? (is it possible the reason for it is nothing to do with contraceptive choice?)

Thus thread might be useful too
