Hi and thank you so much for this query.
I am surprised your gynaecologist would say a lady with last menstrual period on August 7 is expected to be about 9weeks pregnant. this is not true. The
ultrasound findings of 5weeks 3days are very much identical with the clinical estimation which is exactly 5weeks 3days as of 14september 2013. I have a strong suspicion that there is a miscommunication somewhere along the line. You may want to talk with her and find out what the exact information is.
Based on the information you have provided and my clinical correlation based on your dates, this is a perfectly normal
pregnancy judging from the ultrasound and clinical estimation. It stands chances similar to that in every other pregnancy except you provide some new information that pints to the contrary.
Checking for viability has no consequences. Besides, it offers reassurance seen this already conflicting information. Follow up with her and get the details.
I hope this answers your query fully. If you should have any more questions, feel free to ask me and I would gladly respond to them.
I wish you the very best of outcomes wit this pregnancy.
Dr. Ditah, MD
