Bad dreams / : anyone else ???

Brittany • Expecting our second April 2015 ?
So with both my pregnancies I knew right after conception because I dreamed of fish .. But last night .. I dreamed about being on a boat with DH and we were looking down in the water and the fish weren't moving and I thought to myself they were dead .. They weren't floating belly up .. Just sitting on the bottom . I totally freaked myself out because of course I googled it .. And although everyone said it's normal I also read one article were it represents loss. Ive been nervous for week now because my 12 week appt is this coming up Monday .. We will get to hear the heart beat . Can anyone reassure me .. Because I've been worried all day :/
