It sounds like your ex boyfriend has the best chance, from the 9 weeks count of the baby, but what day did you actually have the ultrasound, and what due date did the doctor give you from the ultrasound? Not before the ultrasound but looking at the ultrasound, what did the doc say was your due date?
Hi, I'm checking in from being on vacation, and will try to answer your question. Need a few minutes to read it and work out what you are describing.
