Scared to death

So I went to the hospital Monday night bc I was having horrible cramps, weelllll a pee test, 8 tubes of blood, 20 minute ultrasound and 3 hours in the hospital we found out I just have a uti and that I’m roughly 5 weeks and 2 days

pregnant with levels of 1800 already, but due to my miscarriage this past April (at 5w5d) I’m worried my levels aren’t good enough I don’t have my first appointment until September 19th and I feel like I’m going crazy worrying and praying everything is okay. Every test comes back positive some even pull the dye from the test line. Please tell me I’m not the only one that worries so much with their rainbow baby
