Jessers...you definitely have a girl. The first picture which is much more clear I thought I saw a vaginal slit and with the two newer pictures (even though blurry) make it very clear that you indeed do have a female.
I agree, as we already said before, several of us, it's a girl. I absolutely do not see the slit in the cone that Tab is talking about, even with enlargement, but the second pictures are very clearly a girl.
