Pregnancy help

I had my last birth control shot in feb 2020 and I didn’t get the next one Bc I wanted to go off of it. My first shot was in November and I never had a period after that. So I got my period in April 28th and it lasted 5 days. And then on May 27th I bled at 9pm till 3am. At first it was very light pink and then it was dark brown. The next day there was no blood. The 3 days after that I had no discharge. I was feeling nauseous and my nose bled for two days. I took a pregnancy test a week later and it came out negative. So me and my bf decided to try for a baby. According to my period tracker app, my fertile days were June 4-10 making June 9 the most fertile. So we had sex on the 3rd, 4th, and 5th and he came inside me multiple times. I’m wondering if I can get pregnant?
