I usually get my period on the 19th, on the month of December it was a week late than expected so the 26th of Dec which ended on the 31st. My boyfriend and I had sex on my last day which I think I had stop bleeding. He ended up pulling out but ended up getting precum so I decided to take Plan B 60hrs (3rd of January) afterwards. A week later on the 10th of January I spotted for three days. Does this mean anything? I keep track of my cycle and was expected to get my period on January 28th, I am now 6 days late. Can I be pregnant?
