I'm nervous...

Hillary • Hi I’m 33 and ready to complete my family by adding one more little bean. I have a daughter Adelynn 9 and a son Elijah 3.
So I am about 4 1/2 weeks and I am feeling extremely tired all the time and my breasts are tender but haven't really had any nausea yet... I'm worried because with my mc this is how I was feeling. I'm just so nervous! Can anyone help ease my mind?
