Hello and welcome,
Thanks for your query.
First of all, let me tell you that I really liked the mentioning of your 'Montgomery tubercles', as these are quite prominent in the
areola region of pregnant women. It is good to be well informed.
Although your description (increased urge to urinate, sore breasts, etc) does match that of a pregnant woman, except for the milky discharge which is normally not seen till late in the 3rd trimester of the
pregnancy. Even
constipation is not really common for women in their first trimester, but it can happen.
I would advice you to at first try an over the counter pregnancy test (pregnancy sticks), which will check your urine for beta-
hCG which increases in quantity in the urine and blood of pregnant women.
If this is positive, you will have to consult a doctor for the future course of the pregnancy.
Although I must inform you that this test is not always accurate, thus I would even advice you to schedule and appointment with your obstetrician/gynecologist, if you still feel you could be pregnant even after a negative pregnancy stick test.
Also, when you visit the doctor please mention the milky discharge you have been experiencing.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
Best wishes.
