Hi Heather, Im so sorry for you loss. The one thing i have learnt from BB is that everyone is different and you will most probably be the same. My AF returned exactly 28 days after my m/c but my cycles now seem to be changing from 28 days in length to about 26 days. Whether you actually ovulate in the first few cycles is different for everyone too. I would suggest using OPK for the first few cycles so you can get an idea of what your body is going to do. Lullaby Conceptions is an online store that supplies these at a much cheaper price as well as hpt's.
Best of luck sweety in your ttc journey, we do tend to become crazy women but at least in here we all understand and can be crazy women together !! I hope your stay here is really short. Also you may want to copy and paste your post and put it in the Trying to concieve after miscarriage or loss thread, as this is the Two week wait thread, and there are lots of lovely ladies in the otherone that will be able to help you through your journey.

hugs
treelo
