Serious question

Has anyone ever been on cycle day 22 and haven't got a positive ovulation test? Have you ovulated that late and still got pregnant? I've had dark test but not positive dark and now they are all lighter than any I have this whole cycle. My period is due in 7 days. My boobs dont hurt at all like they normally do when my period is this close.. yesterday my back was hurting and today I have slight pain in my lower stomach. I dont have a clue as to what is happening to me!
