No, not every woman leaks colostrum during pregnancy. Some women do, some do not. It is different with each pregnancy as well. A woman might leak during her first pregnancy and not her second or she might leak during every pregnancy or never during any pregnancy. Either way is NORMAL.
Yes
She should take a pregnancy test. All three of those are symptoms of pregnancy.
The fluids can leak slowly or gush. If you are leaking fluids you should call your OB immediately.
If this is not a first pregnancy it is not abnormal to leak colostrum for the whole 9 months. If this is your first pregnancy generally you will start noticing a clear to cloudy yellowish liquid called colostrum during the second trimester. If you are planning on breast feeding this is the first food your baby will get. It is easily digested and full of antibodies your baby needs to boost his immune system. In the mean time it is a natural moisturizing agent for your nipples. Gently messaging it on your nipples helps get them ready for nursing. A dark or bloody discharge is never normal and should be reported to your doctor or midwife ASAP.
No, breasts leak in the latter part of pregnancy.
