Hi, thanks in advance for your help! my "LMP" was on October 8th/ 2016, only 2 days, less blood than usual... On September 22th, I made a mistake with a friend, he doesn´t came inside me and was very fast. I had intercourse with my husband and finish inside me on October 14th, again on October 22th but doesn´t finish inside me, next day I took an emergency pill. I discovered I was pregnant on November 18th, and made a vaginal ultrasound later on November 29th, the doctor said the gestational age was 7w1d, then, I made another ultrasound on December 30th and got the measure crown rump of 39.7 mm, with 10w6d. Can I be sure its my husband´s baby and forget about the mistake? many thanks, I´m desperate.
