Period after depo

I have been bleeding heavily for a few weeks now after stopping the depo. It doesn’t seem like anything will stop this period.

If I was to take a pregnancy supplement such as vitex or fertilaid, would that stop my bleeding or continue to encourage it?

We are planing on TTC in the near future, and with the depo, I know it can take a while (up to year!) for fertility to return.

TIA
