Your urine pregnancy
test came back negative and the doctor seeing nothing on ultrasound
tell me that you may not have been pregnant. The faintly positive pink line on the tester could be a false positive result which is possible on a rare occasion.
Has your doctor asked you to get any other blood tests?
Ideally you should get a blood test for LH, FSH (hormones of the menstrual cycle), TSH(For you thyroid
), Serum HCG(pregnancy hormone), Prolactin
( hormone for milk production)levels.
Sometimes due to hormonal
fluctuations breasts may secretes milkish fluid.
Your chances of being pregnant appear unlikely. But only your blood tests can tell us what exactly is wrong.
