Hello dear
Understand your concern.
If pregnancy test is negative than no chance of
miscarriage.
But if pregnancy is false negative it may be a miscarriage.
But other reasons for delayed period may be there like:
1. High level of stress
2. Change in life style
3. Late ovulation
4. Excessive exercise
5. Drugs: Birth control pills, tyroid medication, Excessive tea and caffeine
6. Thyroid problem
7. Hormonal imbalance
8. PCOS
9. Endometriosis
10. Dysfunctional uterine bleeding
Also note that
Menstruation required co ordinate action of various hormone that secreted by ovary (estrogen and
progesterone) and brain (FSH and LH).
If any above hormone is decreased or increased there is imbalance in menstruation.
So please do full hormonal profile : Estrogen, progestron, LH, FSH, HCG and thyroid hormone.
That help to diagnose hormonal imbalance.
Also do Follicle study,
endometrial biopsy and
hysteroscopy.
Do regular walking and exercise.
Eat healthy diet
Avoid excessive tea and caffeine
Take tablet meftal spa 2-3 times per day for pain
Drink plenty of watres
Maintain hygiene Wash your vagina with warm salt water 4-5 times in a day
Wear loose pure cotton inner wear
Keep the vagina clean (Not wet)
Hope this may help you
Stay healthy.
