Hi T.-
I suffered a miscarriage early in my third pregnancy. My doctor told me just what you said - wait until you have one normal period - as well as to wait until I was emotionally ready. From the sound of your post, I think you might want to wait just a little longer, just until you aren't feeling so lost. I was really ready for another baby, so right after my period we started trying again, and I was pregnant immediately. The pregnancy was perfectly normal (although I worried a little more in the beginning than I had with the others) and I had a healthy girl.
I never had any pregnancy complications aside from this miscarriage. I don't think that the risk of an ectopic pregnancy is increased by getting pregnant soon after a miscarriage, but it is higher when you have already had one ectopic pregnancy. Miscarriages are more common than I ever realized (one in five pregnancies end with miscarriage), so having one certainly doesn't mean that you are more likely to have another.
If you feel ready to try again after you have had your first period, then go for it. In the meantime, one thing that I did to cope with the time that I had to wait to recover from the loss was to do things that I couldn't do when I was pregnant. I was planning on putting my two oldest girls into a room together when the baby came, so I stripped the wood floor in there, refinished it, and painted the walls. This served as a purposeful distraction and helped me to feel a little better about not being pregnant anymore.
I am sorry for your loss, I know how hard to lose a baby. Take care of yourself, and good luck with everything.
