Confused

Hi. I am totally confused right now. My period is super late (shown in pictures) and I’m kind of nervous. Me and my boyfriend really want to have a baby so if I am pregnant we both will be very happy 🥰. I took a test when I noticed my period did not come and it came out negative, and every since then I have been too afraid to take another to see if it’s truly negative. We had sex around my ovulation time but my apps gave me different days. I have also had problems with irregular periods before but I have never gone this long without a period. (We are very busy people so we bd when we have time)
