Plan B

Hello , I was looking for some advice my last period was Feb 15-20th on the 21st my boyfriend and I were unsure if I had come in contact with some vogue sperm so I took a plan b within that hour just in case! I was sure I hadn’t actually gotten any on me.... I had some spotting 4 days after taking it and now I’m 11 days late on my period and I’m starting to worry 😞
