Hi guys... so according to my last period I should be 7w 2d today... last Wednesday(6w 2d at the time)  I went to my doctor, had an us and we could only see the yolk sac! He said I'm for sure less than 6 weeks .. then today I went again.. had the us again .. and .. only yolk sac again so I'm going back next week! How much should I be worrying? 😫
