I started my period on June 2nd after taking provera for 10 days. I ended my period June 9th. The 20th I noticed a brown spot in my underwear about the size of a dime maybe a Nikel. The 21st I noticed a little more brown in my underwear along with I tiny bit of bright red blood. Today I noticed some brigt red blood. It's not been constant. It's been spotting when I've found it. Could this be do to the provera or could it be implantation bleeding??
