Im 7 days late for my period and i'v been having white discharge from my vagina with no odor and really bad cramps is there a possibility i' pregnant?

Trust the test : Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for for detection. There are many options for cycle control. The vaginal discharge will require an examination.
