Hello,
Thanks for your consult at DoctorSpring.com.
With 3 negative pregnancy tests, chances of pregnancy are almost zero. However, please have a blood pregnancy test to confirm and reliable exclude a pregnancy.
There could be other causes for your skipped period.
Tension, stress, weight gain, ingestion of birth control, emergency contraceptives, ingestion of antidepressants, changes in climate, diet or sleep - these are all possible causes.
Also, sometimes hypothyroidism, polycystic ovaries and endometrial hyperplasia can delay your cycles.
If the blood pregnancy test is negative, please have a complete gynaecological evaluation to know why you are so late. Please have a pelvic ultrasound scan and hormonal levels measured ( FSH, LH, TSH, Prolactin, OGTT, Lipid profile, testosterone, DHEAS ) .
All the best.
Please feel free to ask for further clarifications.
Patient replied :
What could all the signs be
See, many of the signs overlap with those of premenstrual syndrome.
You could be about to begin your period.
Also, they could be due to polycystic ovaries / hormonal imbalance leading to absent periods.
Of course, they might be due to pregnancy, but confirm that with a blood test, since urine tests are negative.
Take care.
