My first pp period was anovulatory, then short LP, then this one. But I carried to full term so I don't know if my fertility return will be the same as yours. To be honest your body's been through so much it doesn't know where it is and so may not be at a 'normal' place in a cycle just yet. I don't know if anything could be classes as 'normal' when you're getting your cycle back on track. It's a pain but I think you just have to wait and see what your body does. The waiting is the hard bit.
