It's even more unlikely it is your baby.
You really do need a DNA test to confirm however.
Hi today me and girl went to da abortion client and they gave her a ultro sound and said she was 15 weeks and 1 day so is still a low chance are??
Ultrasound dating is not exact Shannon. ONLY a DNA test can confirm paternity.
Have the test done. It can be done in utero. There are some risks but since you're considering abortion...
