Dr. I am wanting to know how accurate u/s are? My reasoning for this is my boyfriend and I broke up for two and a half months. During that time I did my own thing. We got back together dec 21 or 22. I left town the 23rd through the 31st. I h ad started my period on the 26th of dec. I know when I got home from my trip we were very active but I still think bout it everyday.

I have had 3 u/s one at 9 wks 5 days, one at 11 weeks, and one last Monday. I was 18 weeks and 5 days. My dr. Told me that I conceived on January 9 or 10th. I worry if I could of gotten pregnant in the begining to middle of december. Do I need to worry. I think about this every single day and don't know what to do. I fear that it isnt my bf kids and i t kills me inside. I don't know what to do. Are u/s accurate as to how old the baby is and the day of conception. Please help.

Hello,

Early ultrasounds are very accurate.  Generally speaking a first trimester ultrasound is accurate within 7 days of the last menstrual period.  So the dates your doctor report should be accurate.

Best regards,

Dr. Downing

So I freak out about this every single night and I am making me sick. So if u/s are generally with 7 days +/- of last menstraul period my other question is this doctor.

I was out of town from the 23 to the 31. The last time I saw the guy was December 15th, 18th or around there no later then the 18th. How often do girls conceive before there period?? I freak out so much. I want this baby to be my boyfriends so much for the both of us but mostly for him.

Do you think I have to worry about this even though I had a period in December and not in January? I am so disappointed in myself and it is hard to deal with everyday. I fear if I have the baby early I will be stressed to the max and I know that isn't good for the baby.

If I do go into labor early is it because my due date is wrong. because I am due October 1. and It is consistant with my 3 ultrasounds and my period I had Dec 26th. Please let me know what you think..
