First of all, I suggest you to undergo one blood test
for beta hCG
to rule out pregnancy
On NEGATIVE test, reasons could be hormonal
imbalance, stress/ anxiety
problem, wt gain/ extreme loss, irregular eating habits etc.
Do some initial investigations to rule out underlying pathology like Pelvic USG, Thyroid profile and other hormone assay etc. So consult with your doctor and take suggestive measures.
Tender breast is MOSTLY due to effect of progesterone
hormone. Use tight breast support for discomfort and take prime rose cap daily. Avoid stress, take healthy diet, control body wt and maintain genital hygiene properly.
Take care yourself.
