Im 19 and 29 days late for AF. Have any of you guys skipped a period randomly?

It keeps feeling like its going to come I’ll get mild cramps but then nothing since July. Around when my period was due i got some pink blood mixed with discharge when I wiped once. My boobs have been so achy the past week and i been bloated for weeks now. Back ache. And ive stopped myself from throwing up three times the past week. I haven’t been as queasy. I Took a pregnancy test every week. All negative I wasnt too concerned about pregnancy bc we used a condom and he didn’t notice any holes or anything. If I did ovulate then it would of been that day according to an app I use that predicts. He didn’t pull out but im pretty sure we’re good. But this is my first missed period ever. I got off birth control i believe sometime in February so its been a few months. But ive been on and off bc before and never missed a period. I have a appointment September 4th I kind of want to take another test before then but im scared .
