10DPO heart palpitations and feeling like I'm going to faint.

Renee

So I'm 10dpo and I've been really anxious the past few days and getting lots if heart palpitations. Just now I felt so funny almost like I was going to faint... I had to lay down. Has anyone had this as a sign of pregnancy? I am getting over a nasty head cold and feel really run down still but colds don't usually give me these symptoms.
