Can Intake Of Danogen 200 Cause Mild Spotting?

I am 32 year old female and I had diagnostic laproscoy last month and was diagnosed with mild endometriosis. I was prescribed danogen 200 for a month which I stopped taking on March 16 . I had some mild spotting on the 20th and then some more spotting on the 27th , which I thought was my period (since my cycle started on the 1st of this month) but this stopped in 24 hours . Is this a side effect of Danogen ? How many days does it take to reverse the side effects ?any help is appreciated
