First time mom

Aya

Hi I am 4 weeks pregnant and I have been nervous about ectopic & miscarriage of the pregnancy. It is like I hear so much about it and my anxiety is already bad. I’m having AF Type cramps on and off and then gas/constipation which is not helping it either. I never feel well rested. I run out of breath going up stairs and I live on the second floor. Someone please talk to me. I need someone to help me . I am so scared
