My last period was in august and i took a test in september and was positive. From that i should be 18 weeks, I went to the doctor and he told me normally uterus/cervix should be at the belly button by 18 weeks but mine was a 1/2- 1inl lower. he said i could just not be the full 18 weeks like I thought and anywhere between 12-15 weeks..which wouldnt add up with my missed periods..i wont be able to see him until a week and a half from now so it would be great if anyone can share similiar stories like this and give me an idea of what is hapoening/ if small uterus's are normal
