I had sex on saturday the 16th of august, the condom broke and within 20 minutes I had taken the plan b pill. I had sex about 3 more times over the course of the weekend (my fiance is away for 16 weeks and got to come home for a weekend). My period app says I started ovulation on the 18th. I have taken this pill multiple times over the past 5 years. Starting yesterday, the 20th I ve been having very weird and vivid dreams, multiple a night...I started cramping a bit this morning, and I m very moody and tired. Is there a chance I could be pregnant?
