Hello,
I suggest you to undergo one
blood test for beta-hCG to confirm pregnancy. It is more reliable.
Besides pregnancy, late period could be due to PCOD, hormonal imbalance, mental stress, over weight/ extreme loss, emotional upset, irregular diet habit, high prolactin level,
hypothyroidism etc.
You must undergo one pelvic
ultrasound scan and complete hormone profile (LH/ FSH, Prolactin, Thyroid, DHEAS, PPBS) to pinpoint the diagnosis. You may require combined hormonal pill to induce & regularize period along with other supportive treatment.
You should control body wt, avoid stress, take healthy low
carbohydrate diet with avoidance of fatty food and sleep properly.
Be well.
