Since you have used the test kit which has been stored in inappropriate conditions, the result is not validated. Please repeat the test with a fresh kit and with a fresh early morning sample of urine. If you wish for an earlier and definite confirmation, please go for the assay of the serum beta-hCG
titres and follow them up with a trans-vaginal sonogram. You do have signs of early pregnancy
, but they need confirmation. Hope you find this information useful. Take care.
