Stress leading to misscarrage

Stephanie
I just misscarraried my 2nd pregnancy at 5
Weeks.  This is my first misscarrage  and my daughter is 2.5. I have noticed that with both of my pregnancys I get extremely stressed to the point where my blood boils. Any little thing someone says to me I get upset about and am not rational. Little things that my daughter does make me so angry. Example running away when I ask her to get dressed, being mean to the dogs, telling me no, fighting sleep, just being a terrible two! My ? Is I know stress can lead to misscarrage. But is there maybe something I am lacking that makes me fly off the handle and get this upset over nothing? Also  I know the hcg levels were not good for this baby I really hope it want my stress that made me miscarry.
