I Am 24 Weeks Today! Found Out I Was 8 Weeks Pregnant September 12th An Due Date Is April 21 2013... Anyway I Had Sex With An Ex July 3,7,11,and 13 Then Got What I ThoughtTo Be An Period July 15th I Have Had 4 Ultrasound And All Are Matching Up To My Lmp. Does That Mean I Ovulated Around Day 14 And Got Pregnant When I Had Sex With My Current Boyfriend On July 28th And 29th? Or Is It My Ex Boyfriend Baby?

You're going to have to wait until the baby is born and do a DNA test.
