Did anyone have his before ?

Diana • Not TTC at the moment .
I got my period one week late which started from August 1till the 6th and I started ovulating on the 12th which glow marks as my ovulation day... The problem is that I started bleeding the 12th. This is the second month that this has happened. (This has happened in May) 
It's like having two periods in one month
Can anyone relate??
