I am exactly nine weeks along today, according to my first ultra sound. I ve had a steady boyfriend for 3 months now, but I was sexually assaulted on, May 4th. He knows about it, along with everyone else. But I was wondering what the chances are that my boyfriend would not be the father. I wake up crying because I m dreaming about it and I can t even imagine what I would do. The first day of my last period was, April 29th and it ended, May 4th. My average cycle is 22-24 days. A paternity test is, +$1,200.00, but I can t go the whole pregnancy not knowing. The last ultra sound I had was done when I was six weeks and five days on June 15th (the day of my first ultrasound) and the attack happened exactly six weeks to that day.
