I went to the doctor and had another ultrasound. The sac is growing, but I am only a little over 6 weeks. The doctor said that the dates could have been wrong on the first ultrasound. He said that my cervix is long thick and firm. he said if I was fixing to have a miscarriage it would be softening up. He also reran my hcg level. If they are going up then that is perfect. With my last blighted ovum, my hcg level were going down. SO I go back to the doctor next monday and have anothe ultrasound. If there isn't a baby then, they will more than likely do a d&c. Please keep praying for me or wishing me luck or whatever you guys are doing. I really appreciate it.
