Just stopped taking BCPs, my husband and I are ttc and I'm concern .. Is this normal?

I stopped taking BCPs by the end Of feb!.. I got withdrawal bleeding the first week of March.. And then for some reason 22 days later I started spotting its a dark brown no foul odor, sometimes I've noticed that it's kinda pink , this hasn't stopped .. I'm still spotting .. Have anyone experienced this after coming off the pill? Is this normal?  I'm worried.. I was hoping to get pregnant this year..
