You already told your mom you might be pregnant, why worry about telling her you took a test? If you got three pregnant results, I'd say you are pregnant, and you need to get to the doctor for a blood test to confirm.
I'd say you are definitely pregnant with three positive results. The only thing left to do is get a blood test done which will confirm that the urine tests were correct.
your writing is difficult to read...however if you took a test and it came back positive you quite possibly could be...the only way to know for sure is to call your doctor and schedule an appointment
if you got 3 positive pregnancy tests then yes you're pregnant. if you want more conformation go to a doctor or clinic for a blood test.
