I’m sorry correction the 12 week ultrasound also gave a due date of 6/8/2022 not 6/6/2022z
The most accurate ultrasounds are the earlier ones. So, going with an accurate ultrasound of a due date of 6/8/2022, your pregnancy most likely resulted from sex between Sept. 9 and Sept. 15.
How did you find out on the 30th that you were pregnant, was it a home pregnancy test?
If you got a positive on a home pregnancy test only 6 days after sex with Mr. Wrong, you were already pregnant by the time you had sex with him. A pregnancy doesn't show up on a test that quickly. This says you were pregnant before the time you had the sex you are worried about.
All your facts and medical evidence point to the sex with your husband as producing the pregnancy. If you are consistently unable to let yourself believe this, it's a good idea to talk to a counselor or therapist. Women with a guilty conscience about their behavior, or deeper worries that the pregnancy has brought up, often let their anxiety over other issues transfer to worry about who is the father. The problem is, no matter how many times she gets her question answered, it's not satisfactory, because that's not really what she is worried about.
With all your facts and medical evidence, you probably do know deep down that Mr. Wrong is not the father. Talk to the therapist or counselor about more amorphous but anxiety-producing issues that the pregnancy has brought up. Look for anxiety in areas like integrity, survival or the relationship with your partner. As you address those, your obsessive worry about Mr. Wrong being the dad will fade.
Katie, I agree with the others. You were already pregnant when you were with Mr. Wrong. You should quit worrying.
