I'm a little scared about paternity of my child...

[vibrantempathy]

Hello, I ended a long relationship back in October with a man I have a child with already. In December, we slept together, during my period, and we used a condom. My LMP was 12/23/2011, so on or around those couple of days is when this event occurred.
  
  Now, I am currently pregnant with what I believe is my fiances child... We were still new to dating eachother and I had a few run ins with my ex and some angry sex that followed...now it's over for good. My fiance and I have had unprotected sex our whole relationship... (high school sweetheart that I lost touch with, truly romantic, and we are goint to elope!)
  
  Even though my doctor says that I conceived around January 6th, 2 weeks after my LMP...I feel worried and afraid for some reason, despite the fact that I was using a condom & on my period at the exact same time.  
Everything checked out on the ultrasound the first time and he said it was "right where I should be" and gave me the Jan 6th date above for an estimate.

What do you think? It's not a matter of who I want to take care of the child, it's a matter of my ex being a red head and looks completely different than my fiance. Even if it wasn't possible i'm still going to worry about it.

Please don't judge...i've had a real crazy last year and I am trying really hard to just be happy and healthy...and some honest and polite insight would do me good right now. What are your gut or statistical feelings on this?

I never got a chance to thank you for your input. We married in June, and our baby is due in September. I am still terrified,  but it's become obvious to me that it's psychological. My ex and I talked it over and whats been bothering me and making me feel sick is that he continues to tells me things like how he wishes this baby was his and despite the circumstances there is "still a chance"...So I've let myself continue to feel uncomfortable. He was hurt when I told him how disgusted I was that we did that. His response was that he didn't realize how serious things were with my husband and I, or he would not have done that...and I just assured him it takes two to tango and we both made a mistake that I will never allow to happen again. I have decided that after the baby comes and things settle down, I am going to seek out a counselor to discuss this and hopefully they will help me decide whether I can overcome this on my own or not.  As of today, things have been amazing and I haven't had any problems. I'm trying to stay as positive and healthy as possible and it's been a wonderful change. I come back here from time to time to read your words, and it brings me comfort. I brought this upon myself and hope to learn a great deal more from this experience...just praying for a healthy baby. Thank you again.

If you felt that was not polite, please excuse me.  I am basing the comment on the fact that people tend to worry about things to some extent based on how much we are hooked on them emotionally, and if we judge our own actions as unimpressive, we stay more hooked on that thing and give it more power to worry us than it otherwise would have.  All of your evidence lines up to the man with whom you have unprotected sex.

MORE THAN LIKELY ITS YOUR FIANCE CHILD

If a doctor gave you a conception date based on an early ultrasound, believe it.  It sounds like you're coping with guilt over your actions, versus truly having some kind of knowing feeling that your ex is the dad.  Protected sex when menstruating doesn't produce a baby, unprotected sex when ovulating does, and the doctor is helping you see this is true by confirming things with an ultrasound when it is still early enough to give you a good count.  Try not to go into an endless loop over this, you have enough other things to think about.
