I took the plan b on August 30 and had withdraw bleeding on September 6-10, didn’t get my regular period that month of September, and took a pregnancy test on October 23, 3rd day of my bleeding and I did the test at the doctors, it came out negative. I was only worried bc the bleeding I had at Octob...

If I experienced withdraw bleeding a week after taking the plan b, does that consider I’m not pregnant? Also month and 3 weeks later since the incident I got this period but it was heavy but light than my regular heavy period.
