Stopped BF 6 + months but still have milk TTC and late ovulation

[Victoriaspa]

Hi, I have been trying to conceive for over 6 months, and been tracking ovulations which is around day 20 on a 27 day cycle.
we conceived very quickly with the first, and now I’m beginning to think it’s the breast milk messing everything up.
has anyone had any experience of a short luteal phase or delayed ovulation, anything that worked? I’ve got a fertility clinic appointment next week and hoping they can prescribe something? Has anyone been given anything to tweak ovulation dates without going down IVF route?

Soy isoflavones brought my ovulation forward this increasing my luteal phase. I also used progesterone though to support the luteal phase.

But I believe we answered this on your previous thread..?
