I have already done pregnancy tests and all negative, should I repeat?

Can you help me. I had my period delayed 15 days ago I did 2 tests of pharmacy gave negative, 2 of blood also negative and an ultra transvaginal gave thickening of the endometrium in 7cm, the doctor said that it was either a menstruation that was for vim or a pregnancy that was still I do not know what to do, I want to do another blood test, I feel a little colic and my breasts hurt a lot, mainly the nipple.
Expert answer:

What is the use of a new blood test if your problem has already been found, if it is a pregnancy in the fallopian tubes the gynecologist will conduct the correct treatment, probably waiting a few days and repeating the Transvaginal Ultrasonography Examination, if it is a menstruation that is to come wait a little that she is going to go down or the gynecologist will medicate with medicines for her to come down. You need treatment, not new exams. Stay calm and calm and trust your doctor that he will conduct your treatment, if you do not feel safe change your doctor, but there is no point in wanting to do more tests.
