Very scared of miscarrying.

Hey guys I'm 4 weeks & 4 days pregnant. I've been having period like cramps that come and go away but mostly come at night since I found out I was expecting about 6 days ago. I don't have any bleeding and period is 5 days late plus positive clear blue digital. Also my boobs are sore (mostly the nipples) and my breasts have these enormous veins on them. I'm so afraid of miscarrying that I spend most of my day reading the horror stories online and on the glow community. I've been taking 81 mg of baby aspirin and my prenatals everyday since before I found out. I feel like I've been stressing myself out and peeing on sticks every morning to see if the baby is still there. How can I stop obsessing over miscarrying? This is my first pregnancy. I wish I could fast forward to 13 weeks already. 😩
