Wanting to keep testing after positive test???

Am I the only one who keep wanting to test to make sure your still pregnant 😂 I have a few symptoms(morning nauseousness it's gotten better tho since I make sure to eat a bigger dinner and eat a banana when I wake up, sore boobs, heavy bloating, and peeing none stop) but it's like I still can't believe it! I'm very terrified of losing this baby (first time being pregnant)  but I keep doing positive affirmations! I just want my 8 week appointment to get here already it's on the 16th! I'm 5 weeks today! Does anyone else feel this way?
