I don't know about your fertility after having one. I would think that it shouldn't affect it.
I think (but not sure) that a lot of women have chemical pregnancies, but don't even know that they were pregnant. They get their period before they would have suspected they were pregnant.

Not sure though...Where is Christy when we need her with all her knowledge on this...or Kia???

I had a chemical pregnancy/miscarriage back in March. It doesn't affect your fertility. I would take advantage of the month following because they say you are more fertile after you miscarry. BTW, it didn't affect me at all because I am now 10 weeks pregnant.
