Please tell me this is my rainbow 🌈💝🙏

Earlier this year I suffered an incomplete miscarriage and last month a chemical pregnancy. I ovulate early cd9 or cd10. Today is cd17 and I tested knowing it is quite early but the three frer I took (so glad I peed in a cup to be able to ensure it was not just a faulty test) came back with faint lines. Please, please, please let it be a sticky bean and a healthy pregnancy and baby. My first one was also a rainbow baby. I feel so thankful but so scared too. What are the chances the three tests are faulty???
