May 5-May10: If the ultrasound were 100% accurate (Its definitely not) you would've conceived close to May 5-10. With irregular periods this seems most likely. If your ultrasound dating is from the 1st trimester this timing is close to certain, if it was a 2nd trimester ultrasound the guess might be farther off.
