I have a question. If I had my regular period October 15-20 and had sex the 31st and took Plan B one step around 7-8 hours later, what are my chances? About a week after taking Plan B one step I started having what looked like spotting by then turned into regular bleeding for about 4-5 days. I've had other slight symptoms like tiredness, bloating, odd stool, and nausea mostly. I took the pill because the condom broke and I didn't want to take any chances..
