Print this page Email this page Post a comment Subscribe me Add to favorites Remove Highlighting Edit this Question I had my period May 12, 2007, letting me ovulate approximately the 26th of May. I had sex with my husband on that day on got pregnant. I also had sex with another guy on the evening of the 24th. He did not ejaculate nor did he pre-ejaculate inside me because I saw the pre-cum come out of his penis. He never ejaculated. I ended it with him. Now at 20 weeks my ultrasound says I could Have concieved on the 25th. Now I'm scared. Can I be pregnant with the man not my husband? How accurate is the ultrsound? Your period started on May 12th and you are thinking you ovulated on about the 26th of May.               You had sex with your husband on that day and think that is the act of intercourse that led to your pregnancy.               However, you also had sex with another man the evening of the 24th, but you seem to be quite certain that he did not ejaculate nor did any pre-ejaculation get into you.               Now ultrasound says you could have conceived on the 25th and you are scared.  You wonder if you could be pregnant with the man who is not your husband.  This sounds fairly unlikely.       How accurate is the ultrasound?  Well, certainly not to the day!!!         What are your plans?   Key Words:  period, ovulate, sex, pregnant, another man, pre-ejaculation fluid, penis, ultrasound, accurate
