Anxiety before hcg test + first scan

Hey everyone! I am 4 weeks 5 days today, and had my first blood draw to check hcg and progesterone this morning! This is my first pregnancy ever, and while I’m so so excited I’m also very nervous. I have no reason to think that anything would be wrong, but I still feel so much anxiety. The only symptoms I’ve had are feeling verryyy tired, tender boobs, weird cramping that feels like my period will start for about 15 seconds then it goes away, and a pulling feeling in my uterus when I stretch or arch my back. I’ve also had an INSANE sense of smell. The cramps have lessened a lot since last night which has me worried:( I guess I just need some reassurance. 💗
