I am a little concerned, last month my "period" was only one day completely stopped and spotted two days later very little. I had a little brownish sticky discharge in my underwear a few days ago. could this be implant bleeding? My periods have always been unpredictable. My boobs have been sore all month and it is the 18th. I have woke up three days in a row nauseated and dizzy not throwing up but very dizzy. Have had headaches I can not get rid of. Im really worried, I already have two kids I wouldnt mind another just not right now I just finished college and not the best timing but I need to know if this could be implant bleeding or just a weird period? please anyone give me some advice. HELP!! lol
