My last period was on 2 to 5 april, i started mirelle and was on it for 2 weeks then stopped as i kept forgetting to take the pill, my period is now about 5 to 6 days late, at 1 day late i took a test it was negative, should i retest for pregnancy?

Maybe retest in 1 wk: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) 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.
