This is what is happening to me an I'm wondering the same I'm very scared that my first born is the only child I will have..my boyfriend an I have been trying for 3 years an 2 times have ended in m/c
chances are, you'll be able to have more. its possible she'll be the only one you'll be able to have, but generally just because you've had 2 miscarriages doesn't mean you can't have any kids. like jenkaye said, when the time is right, it will happen.
I'll bet you will be able to have more. I have had 2 m/c but i also have FOUR healthy kids. Just wait, when the time is right i think it will happen.
