Urge to test. When's the earliest DPO you got a BFP

Wayyyy to early to test. Should have ovulated on the 9th. But if I go by my CM looks like I ovulated more like the 6. Anyway the urge is so hard. But I feel like I'll just be disappointed. It's like I'm prepping myself for. BFN next week. Ugh. The wait is terrible I think I may take a test on Wednesday
