I am 12 weeks and 1 day but I'm so confused my first appointment my dr thought I was 10-11 weeks almost 12 weeks cause baby was more developed then 8 weeks .. I go in 2 weeks later dr said baby measures 10 weeks .. then last week I go in (1 weeks later from the last should be 11 weeks 1 day ) baby measurements were 10 weeks 5 days then today I do in only a week from my last baby is measuring 13 weeks 1 day so they put me at 12 weeks 1 day cause they are not sure when I'm due ... I'm due between march 22 and April 17th that to me is such a big gap .. this is my 5 th pregnancy 6th child I am excited but I hate not having a real date to mark down..
