Hi, I discover that I was pregnant the 27th of december, I went ot my doctor last Friday, I was supposed to be 6 weeks pregnant since my last period had started the 28 of November. He offered me to do an early vaginal scan since I had two previous miscarriage. When he did the scan, he dated the pregnancy to be around 4 weeks. He told me not to worry, but I am very regular (28 days) and I don t understand how I can be two week less pregnant then I am supposed to be.
