I am about 34 weeks pregnant on November 30 and my last menstrual period was on March 27 to April 2. I had unprotected sex on the 9th of April with possible father 1 and sex with possible father 2 on the 3, 13, and 20 of April. On may 26, the ultrasound showed that I was 7 weeks 4 days..but if the first two weeks of pregnancy doesn t count, does that mean I was only 5 weeks 4 days and that i conceived on the week of April 18-24? Help please
