I wanted to know your last menses date. In any case , irregular periods
do have a possibility of pregnancy. So you should do a blood or urine test to rule out pregnancy.
Also your symptoms of breast tenderness, tiredness, fatigue , excessive sleep are seen in pregnancy.
Incase your test is negative, you can consult a gynecologist for an internal examination and ultrasound. If both are normal, then you can go ahead and take progesterone
tabs like regesterone
or meprate for withdrawal bleeding (ie to get your periods)
If your next 2 cycles also remain irregular, then you need a complete evaluation with blood test for hormonal levels like Serum TSH, LH, FSH, Prolactin and Testosterone
Please donot take any self medication
. Visit a gynecologist and be under supervision.
