Just wondering if anyone out there has a really short AF and still managed to fall pregnant naturally?

I have 2 DS's who are 9 and 12. After having DS2 I developed amenhorea (loss of period). Ive since gotten off the pill and AF has returned but is only ever 2-3 days and extremely light!

I'm currently TTC and wondering if it's going to happen or if I should be seeing a specialist?

I already get acupuncture, take herbs, vitex and I have high iron naturally. Cycle Length is 30-32 days.

Thanks x
