argh.....

some info maybe tmi but please help me understand. So my last few months of af have been off ranging anywhere between 22-34 days. August 24th was my lmp. on Sept 3rd my husband and I baby danced and after I had slight spotting. Sept 3rd was my 11cd and from what I understood from Google on ovulation bleeding it can happen on 11cd and.... ok so I'm confused because it said that slight bleeding can indicate egg is released. So should I count my 2ww from yesterday?
