I have a couple problems... one is that you wouldn't KNOW that she's a pokemon until after the RP starts, and two is that you can't be 'a tiny bit pokemon'. Due to the fact that pokemon DNA is incompatible with human DNA, it's safe to say that it's either all or nothing as far as that goes... but, you wouldn't know why the miscarriages happen, and may have come up with some (false) excuse, or have the doctor come up with some (somewhat true, but not the main problem) reason as to why it's not working.
