I had my period about 2 weeks ago as normal (i normally have heavy periods every 28 days for 5-7 days). Over the past 4 months i have started having spotting between periods and the same happened again this month last tuesday however this time they wont stop (so i have had a steady flow for 6 days). I started going to the gym last monday (i did 5 days of gym) then had saturday, sunday off and went to the gym again last night and tonight. will they stop and should i be worried???????
