How Long Does Implantation Spotting Last?

Implantation spotting rarely lasts more than 1 day, states BabyMed. Implantation spotting is often lighter in color than menstrual bleeding.

When a woman experiences implantation, she may feel some minor cramping, notes WebMD. This is normal and it should resolve on its own. Implantation bleeding often occurs 6 to 12 days after conception. Due to the timing, many women mistake the spotting for their period. If a woman is worried about implantation bleeding or pregnancy, she should consult her doctor. Sometimes, the bleeding can be due to other causes such as sex or ectopic pregnancy. Miscarriages can also cause abnormal spotting.
