QuestionMy lmp was Dec 29 2011. I had sex with an ex Jan 06 2011. I had sex with a current bf Jan 9th, 14th, 15th, 21st, 26th and 29th all unprotected. My cycles have always been irregular from 29 days to 40 days. I have taken 5 ultrasounds which have all given me the due date of October 19th and conception date of Jan 26th. Ultrasounds was at 6 weeks, 8 weeks, 12 weeks, 16 weeks and 20 weeks. Could Ultrasound be off and could I gotten pregnant earlier with guy 1.
AnswerIt is extremely unlikely that you got pregnant on the 6th, based on the length of your periods, the time you likely ovulated, and the date of your LMP. Early ultrasounds are usually pretty accurate, but they can have a margin of error. Obviously, I can't give you a 100% answer, though. Only a DNA test can do that.
Best of luck,
