"So my girlfriend took plan b on the 26 of February and she was ovulating during the time the slip up happened an her tracker said she would get her period on the 10 of March but her period always come 5-7 days after the expected and it came 5 days after and she got it on the 15 and it worked she got her period for 4 days like usual. Now it's March 29 and she is spotting and I'm freaking out what could be the cause of this"
