Patient :Hi. My boyfriend had a one night stand on 10/31-11/1/12. The girl said she was pregnant 4 months later. According to her ultrasound she conceived 11/9 with a due date of 8/2/13. Her lmp was 10/26. She had the baby 7/29/13. Is there a possibility there is someone else the girl has lied about a lot so I don't trust her and for some reason no paternity test has been giving. I assume she has regular cycles. Thank you in advance.
