Positive at 10 DPO— how to stay positive

Hello ladies. I just found out I’m pregnant, have been trying for a year and this is my first. I told my parents and they were so excited they told everyone they know which I don’t mind... it’s good news. One of my cousins gf just had a baby and she messaged me saying I shouldn’t have announced so quick cause I could have a tubal pregnancy like her friend did. I was super happy until she told me that, now I’m looking for ways to stay happy and not worried. Any advice?
