Sorry to hear that (but congrats on your new babe)!
I've BTDT w/hemorrhages twice - once after my DD's birth, and once from a ovarian cyst.
All the suggestions are good - beef, dark greens, beans, beets are all good. Also, to the extent that you can, and it's safe, you're going to need to get moving and get exercise. Your diet & supplements will provide the needed iron, but then your body actually has to have an increased demand for oxygen to ramp up production of the hemoglobin. I remember shuffling around the block after my ovarian cyst (I had 2 units transfused, but was still seriously anemic). It took forever, but it helps.
I'm guessing that the dizziness may also be related to a bit of low blood pressure. Especially if you lost a lot of blood, your blood volume is low, which can make your pressure a bit low. Making sure you're eating plenty of salt will help with that. Try cheeseburgers with ketchup (ketchup is salty).
Hope you feel better soon.
