Confirmed pregnancy - Question!!!

I had a period April 13 for 5 days . Ovulation in May. So I missed a period in May, took a test end of May, not pregnant. Take 2 more in mid June, not pregnant & no period. July still no period, forgot to take tests cos I’ve been busy with a new job and thought missed periods were stress related. Come long weekend in August I started having symptoms, I take a test and I’m pregnant. Get an ultrasound a couple weeks later to only find out I’m 8.5 weeks pregnant. So that means I got pregnant mid June. Has anyone ever heard of anyone getting pregnant way after ovulation period & my last period was in April. I am a little shocked about the dating. Anyways still a blessing. ☺️
