they couldn't find my daughter's until I was 13 weeks they had tried to get me to get a abortion basically and I declined and said my body would do it on its own and if not then I would consider it but I was having some back pain and went in and they FOUND IT she is now a healthy 6 year old@singleandstrongmom
I had mine at 9weeks and they found one but when I went to my 8week appointment they said that if they tried to find it then they might not be able to.
