Early ovulation and early testing?

Oh my this Is unexpected. I know how babies are made ..but I had my period March 25 to 28 and only had sex April 1 since it was right after my period ... It not my fertile week sex is fine. What are the chances sperm lived peacefully in my whoohaa for a week. (My tracker said I'd ovulate April 8th) I took a test 7 days later on April 15th since my 3 year old pointed at My belly and said baby...like what?

The most positive quickest test I've ever taken.

Likely hood of ovulating early my period is clock work 28 days .. so I'm not due for my period dor another 7 days. So it seems like it's pretty positive pretty quick.

Just looking for others insight.

Lord help me 3 under 3 ....
