The doctor told me today that my blood test showed 21 MIU/ML's. She gave me a chart that says I am 1 Day- 1 Week pregnant. I figured I was due July 17th... But the website also said I conceived on October 27th... Meaning I am more than 1 week pregnant... I'm confused... I want to have an accurate date because I am a teacher and need to know if I will miss any school... I realize that my mid wife/ doctor will be able to tell me eventually... Any help you can give me on my due date or how many weeks along I really am would be greatly apprieciated.
