So my last period started on 10/08/15 and I had sex on the 14/08/15 (very last day of period hardly any blood) there was an 'accident' and I'm not on the pill (makes heart condition worse) and now on wondering whether this is a risk or pregnancy. I think I ovulated today (22/08/15) so is there a risk of pregnancy with me having sex on the 14/08/18????
