help please don’t be rude

please don’t be rude. my anxiety is bad with pregnancy. the photo shown is my april cycle. i had protected sex the 17th and 18th of april. he did not finish while inside even though we had a condom. i got my period on the 20th and it was pretty normal. i have yet to get my next period and i’m currently 11 days late. i took a test on late day 5, first thing when i woke up and it was negative. i’m probably okay but like could i be pregnant?
