Hey ladies I need some help calming my nerves lol I started my period may 25th-29th I took a PLAN B pill june 4th so I started my period back up from the 5th-8th. I know with plan b pills your period is still suppose to come on regular schedule and my periods are normally spot on. But I still haven't gotten my period again. I've taken wayyyyy to many test and all negative so I'm not sure why I still haven't gotten it
