If you are experiencing light spotting that is pinkish brown in color and only appears when you wipe, it could be due to implantation bleeding or a late period. Implantation bleeding occurs when a fertilized egg attaches itself to the uterine lining, causing slight bleeding. This can happen around the time your period is due and may be accompanied by mild cramping.
However, if your pregnancy test came back negative, there could be other reasons for your symptoms. One possibility is that you are experiencing a late period. Late periods can occur due to various factors such as stress, hormonal imbalances, changes in weight or exercise routine, or certain medications.
It's also important to note that home pregnancy tests may not always detect pregnancy accurately, especially if taken too early or if the urine is diluted. If you still suspect you might be pregnant despite the negative test result, it's recommended to wait a few more days and take another test or consult with your healthcare provider for further evaluation.
If your symptoms persist or worsen, it's advisable to seek medical attention as there could be underlying health issues causing these changes in your menstrual cycle. A healthcare professional will be able to provide a proper diagnosis and guide you on the next steps based on your individual situation.
