Worried and sad

My last period was June 13th and I'm on the 4th day of my fertile window and gotmy deposit probers shot. My chancesnof pregnancy on here are 27% high. I've been having j protected sex almost everyday. The dr pressured me into the shot after I got a negative pregnancy test but it is to my understanding that this could be a false negative b it could be really early on pregnancy. I have been spotting a little. White sticky discharge right now, was just having slimy clear discharge. And I'm tired all the time now...I'm hoping I can still have his baby. I wanted to be pregnant but the dr pressured me I yo It and made me feel like I was being stupid if I postponed it. Help. Please don't question how I let her pressure me Into it. Is it possible I could still have a baby ifbim in my 4th day of my fertile window?
