I had sex with my boyfriend about 4-5 days ago and took the Plan B the day of... We had sex again (Day 4 after taking Plan B) and everything was fine until I went to go to the washroom and noticed I was bleeding a little... Didn't think much of it as it could have been a little scratch from his nails or something... but suddenly as the night went on it became heavier and heavier, and starting getting light cramping.
This morning it was pretty heavy and I'm still cramping a little (Day 6 now)... it's not normal period blood, it's less thick as normal blood would be.
I had my period previous about 9 days prior to taking the Plan B.
I'm not worried about being pregnant... I'm worried if I should I be concerned about something more serious?
