Am I pregnant? Young and scared

My period is 5 days late, with a normal cycle of 28 days that’s usually always on time. I am 18dpo, one of the photos attached shows when I’ve last had my period. During ovulation I used a condom, and knowing that I had sex prior to ovulation leaves me scared, but wouldn’t that show up on a test by now? I have thick, white, discharge or no discharge at all throughout the day. I have cramping on and off throughout the day. But no other symptoms. I took one pregnancy test two days ago, one yesterday morning (picture below) and got two negatives both times.
