Not sure how I got pregnant

I mean obviously I had sex yes 
But it's just so unreal to me bc
The last time we had sex was way
Before ovulation. I know sperm can
Apparently live in you for up to 5 days
But we had sex at least 9 days before ovulation
On day 5 of my cycle 
I was still bleeding even. 
But here I am knocked up..... 
What the hell 
Not complaining 
but HE is NOT going to like this 
At all. I actually think he will leave me and tell him it's my fault bc he asked if I was close to ovulation and I said not at all so he took that as the green light to finish in me which we haven't done since my miscarriage, bc he didn't want that baby. 
He's going to think I was lying 
But... I was on CD5.....
