Well my last period was around 21st feb ,took a preg test and pos!!Went for early scan on thursday and he measured 5 weeks preg,there was a sac but nothing else,got to go back in 2 week to check but i not hold out much hope.I just confused as i say im 7 weeks but like i said he say 5 so who is right,is he just going off measurments.As if i say im 7 there should of been a heartbeat.
