I used it earlier in the year after a chem pregnancy left me AF-less for months, it gave me a heavy period, then when I went to do a FET cycle, my lining wasn't great which I put down to the provera but thats just my guess ( cycle cancelled anyway cos they missed my O), I was sort of pleased I didn't do the cycle cos of the lining.

So, because of my experience if I were in your shoes I would wait ( I know its hard)
