Hithanks for using Chat Doctor. As you written that on 11.3.10 you used condom and spermicide, while on 11.8.10 you had unprotected sex, and your EDD is on 7.30.11. On the basis of EDD by USG one can not be sure about answering your question, but one can be almost sure based on the information provided by you that father of expected baby is the person with whom you had unprotected sex. To confirm it now there is a only way to undergo DNA test. Thanks
