just some reassurance

K
Took clear blue digital sunday 15th which dated at 1-2 weeks. And then by my dates I should be 7 weeks by the dates of clearblue should be 6 today. They say between 5-6 weeks. Had a scan they measure a fetal pole at 3.7mm and a sac and seem not concerned just that my ovulation was a bit later bla bla and I have another scan on Feb 14th. I'm just a bit nervous after three miscarriages last year. Hubby won't talk to me about it and told me to expect the worse. Someone reassure me. Xxxx
