So scared

I'm so scared of another chemical pregnancy I have been a test crazy person. I have legit been testing every 12 hrs for 2 days since I got a faint positive on 10 dpo. I could use some reassuring words cuz it's all I can think about like getting my next fix I'm just sure I'm gonna dip and the lines gonna be gone! I even been tossing and turning just thinking about fmu. Help me!! I got pregnant the very next cycle from my chemical so that makes me worry so soon as well!! A lot of you women are so smart!! I need some advice other then my husbands just relax!
