Hello and welcome to HCM. Thank you for your query. It is most important here for us to know when you conducted your pregnancy test, and if this was ruled out too early. Your symptoms could be relating to pregnancy, especially because you have not attained your period yet. Have you always had irregular periods or have they been normal and this is the first time they are late? This is also an important question. Now coming to the pregnancy test that you should repeat. Please get a home pregnancy (urine) test and check your status with an early morning urine sample. I would also recommend you to visit your doctor at the earliest and get examined. What is your age? And do you have any other problems relating to your menstrual cycle? All these are important questions, and you will have to discuss these in detail with your doctor. The next thing I would want you to do is to send your urine sample to the lab for examination. As a few of your symptoms could be related to an infection as well. Once an infection is confirmed (if at all), please initiate the required treatment after reporting to your doctor. If an infection is ruled out, undergoing a screening for sexually transmitted diseases would also be a wise option. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
