Hello,
This can be due to low Beta HCG hormone, up-to that day when test was negative, we can get a positive pregnancy test up-to 10 that day after expected date, pain might be due to expected periods and discharge may be spotting due to menstrual flow. Hence, in this case repeat pregnancy test after 7 days again to confirm is best.
In ectopic pregnancy, also, pregnancy test comes negative but it is only 3 percent and associated, with
severe pain in abdomen on one side,
dizziness, spotting per vagina, and nausea and vomiting, stress is also a cause, dietary change, exercise, thyroid are other causes. Breast feeding is also a cause, PCOD and early
menopause can be a cause is missed periods. Birth control pills can cause in missed or
irregular periods, medicines for
hypertension be the cause for missed periods, simple fever due to any cause can cause missed periods.
Take care. Hope I have answered your question. Let me know if I can assist you further.
