Okay Ladies Question Time!

I stopped taking BC beginning of March and had withdrawal bleeding the 12th. I have yet to have aunt flow. But, bc I had EWCM I though I would use ovulation test. I used it Saturday and it came back first line darker then 2nd (LH surge detected) I then used a digital test the next day Sunday and it stated I was at my peak. My SO and I had sex Friday and Sunday because He's only home weekends right now, what are the chances I could conceive(ed)?!?! Hoping this is it but, is it too soon after stopping BC to get pregnant?!?! Help!
