The 4 Rules of Implantation Bleeding
While every woman is unique and every situation is different, these four conditions do hold true for many of us:
1. Implantation bleeding resembles spotting. It does not get heavier as the days go by.
2. Implantation bleeding usually lasts shorter than a regular period. One to two days being most common.
3. Implantation bleeding usually occurs anywhere from 6 to 12 days past ovulation, assuming you had sex during your fertile window.
4. Implantation bleeding is often pink or rusty brown. It is rarely red.
Only one in every three woman notice any sort of implantation bleeding. That means two of three get pregnant without any bleeding.
