Mood swings

I’m 6wk 4days and my mood has been off the charts today! I have been so cranky all day and I ended up exploding over everything tonight that I’m getting anxious because I just want to calm down and I’m worried that exploding today has caused stress on my baby and pregnancy! This is my 5th pregnancy and I have never been able to make it past 6 weeks till now! And now I feel so guilty and terrible for being so irresponsible and not thinking of the baby before exploding!
