Hi, i have had my period the end of Feb. going into March. My last day was March 5/6th. But I recently started spotting on March 16, and on March 17th it was a little more heavy than just a spot, and then randomly back to just spotting. Today is the 18th and in the morning it was just spotting, but as i used the restroom this afternoon its a bit more heavier than spotting. and now back to spotting. what can this mean?Please help.
