Was 12 hours & then 20 hours late taking my birth control twice last month. i took the rest of the pills as normal. i also had unprotected sex. no period on my week of placebo.. negative test but intense cramps, & clear discharge. could i pregnant?

Hard to guess, but: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or 1 week after starting a "weird" 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.
