Period ended 12 days ago.

And just 2 days ago i had brownish with tiny specks of pink or red discharge.

But much more brownish.( For a day and a half)

Anyways. Im confused as so i do not know when i ovulate because I do have VERY IRRGULAR periods.. comes when it wants to. I Do have a 6yr. Old.

And with her it was a suprise because i havent had my period for months before finding out i was pregnant. Doc said i must have ovulated even if i havent had my period. So any ideas whats going on?.
