My periods have been irregular ranging anywhere from 30-49 days. An average cycle is around 38 days for me. Now I m on day 54 of my cycle and still have not had a period. I ve been sexually active about once a week so I took a hpt on day 51 of my cycle and it came back negative. However, I ve had some pregnancy symptoms like headaches, being nauseous sometimes, heartburn, bloated stomach, and urinating more frequently. I have had a bunch of stress recently too though like getting a new job a couple weeks ago, trying to find another job, and having a long distance relationship so I m unsure if that is why I m not having my period yet or if I could be pregnant. I ve just never gone this long without a period.
