Bad week

So this week actually started out good becasue My husband will be back from Iraq soon. Yet Monday we found out my 4 year will have to have her tonils out next week before hubby is hoem. Than on wednesday night I Found soem lumps in my breatss and went to the doctor on thursday. Hoping she would tell me it is nothign but she is not sure and she managed to find 2 more. She is not sure what it could be so of course I am worried. I go on the 3rd of july for a ultrsound. Yet I am worried. I am only 24 I have 2 small kids and really don't have the time for more problmes
