Hi I need help determining my babys father! My last menstrual period was August 20, 2010 I slept with my boyfriend August 13,14,15, & 26th. i slept with my ex sept 5 & 11th. i went to the doctor on october 8th and had an ultrasound & she said i was 7 weeks. i got to hear the heatbeat and everything. Im still confused though on who the father might be, please help!
Hi, Your ex is the father of your baby. First trimester ultrasounds are very accurate in estimating gestational age with an error of just 1 week. You would have had to have conceived 5 weeks before 8 October, to be 7 weeks on 8th October. This is because we always time the pregnancy not from day of conception but the last menstrual period. So the confusion of 2 weeks, as those two weeks represent the follicular phase of the cycle you conceived in. Hope this helps. Regards.
