Okay to give some backstory. My periods are regular. Never late. My bf got a vasectomy five years ago. we had sex the last day of my ovulation cycle. He didn’t cum neither did we use a condom. My period was supposed to start on March 13 but now I’m two days late. I know that the time change can mess up your period but I’m really worried that I might be pregnant. I took a pregnancy test and it’s negative but it could be a false negative. What are y’all’s thoughts? Am I pregnant or am I stressing myself out?
