My cycle was expected to come on jan 1 but it haven't came on now i am 11 days late and i have lots of discharge instead of my cycle could i test now and get accurate results?

Pregnancy worries?: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.
