I have been experiencing irregular symptoms for two weeks after taking the plan b pill. I had unprotected sex (he didn't finish inside me) a day after my period was over and I took plan b the next. I had no irregular symptoms for a week, and then started spotting. It was a brown colour (which was normal considering my period just ended) but it has been over a week now (two weeks after plan b) and my discharge is still abnormal, being tinged-brown and There isn't as much as usual. Is this something to be worried about?? The only other symptom I've had is breast tenderness and some mood swings.
