Hello, id like to know something. Less then a month ago, i started to feel sick, So i took a home pregnancy test. And it was positive, i took 5 of them,All the same. So i went to the doctor, to have a urine test done, It was also positive, Then i had a blood test and ultrasound done, but they told me they saw nothing, And the blood test was negative, But im missing my period again now. And ive gained alot of weight, And i have all the signs that i am. could they be wrong? what should i do?
