hello, i am currently having the exact problem you are. i took plan b within 8 hours and i’m feeling symptoms almost a week after taking it. i’m very confused. and would like to know what’s going on as well.
Yes, this is probably side effects of plan B. It takes a while for those hormones to work their way through your system. Plan B is a huge whopping dose of hormones which is how it works. They linger. You will be irregular and have hormonal side effects for 2 to 3 months after. Plan B is pretty effective and this sounds like side effects from the drug. If you are concerned about still being pregnant, wait a full week, take a p test. good luck
