Currently 2 weeks late. took four at home pregnancy test. i spotted for 3 days light pink to darkish purple blood. what is this?

Not pregnant: With 4 negative HPTs it would be unlikely that you are pregnant but a blood test from the doctor can be done to be 100% sure. The spotting may be your period for this month. Periods can be variable even in someone who is usually "regular". Stress, illness, medications can interfere with your cycle.

Several things: How far apart were the home preg tests? Give at least a week between tests and use first morning urine. If you did 4 tests 1 week apart and all4 neg highly unlikely you are preg. Many other reasons for spotting that you would need gyn eval to help sort out. Hope this helps. Beat of luck
