### input:
hi, I have been having pregnancy symptoms. but every test is negative. my last period was suppose to be January 25, 2014 but it came on January 28, 2014 . It was a really light flow and didn t have the normal clots in it. I didn t cramp and it last for 5 days off and on I wore a pantiliner the whole time. I took a test three days after it stopped and it was still negative. but this week I have had sore tender tender breast and my periods not due until February 24 my husband said the inside of my lady part has a bluish look to it and that my breast are enlarged and darker. I had this belt I wore three months ago and I can not wear it any longer because my hips have spread for some reason. I have been to a health department and they think since me and my husband want a baby and a pregnancy that we are both thinking every symptom is pregnancy. but how do you explain the bluish vulva? I really need answers on what I should do.

### output:

Dear Madam, I do empathize your concern. However, the first cardinal symptom of pregnancy is missing a period (though occasionally some women may get menses in first couple of months of pregnancy). You had periods, however, somewhat lighter. This should be taken into consideration. The other symptoms follow about one or two weeks later. They are:* Nausea and vomiting with pica: You do not seem to have them.* Frequency of urination which you do not seem to have.* Breast changes: - Engorgement and tenderness which you are having-Dark discoloration of the nipples and areola: This also you have noticed. Along with this, the size of areola also increases. Are there any tubercles under the areola? They will go more in favor of pregnancy. - Secretions from the nipples: They will be strongly supporting the pregnancy. We do not diagnose the pregnancy only on the symptoms; they have to be supported by confirmatory evidences like pregnancy test and/or clinical findings. However, your pregnancy test is negative. Madam, I feel you have carried out this test rather too early. These tests may report false negative in the first week after missed period. Hence, repeat the test after about 4 days; however, going for Beta Chat Doctor test would be more reliable. This is highly specific and sensitive test. The levels of Chat Doctor > 25 will confirm the pregnancy. If this test also reveals that you are not pregnant, you have to accept the diagnosis and attribute the symptoms to some other cause like increase in weight or so. Let the bluish discoloration of vagina be confirmed by Gynecologist instead of a lay person like your husband. I hope this has given you a valid clue to resolve your dilemma.
