Conception ?: With your description, conception probably occurred in third week in April. Unprotected sex with "no ejaculate" still may have semen with sperm, and this form of "birth control" is frequently unsuccessful. Conception later would not coincide with the "early ultrasound date's" fetal size, which is generally very accurate at that stage.
