Frequent periods can happen because your hormones may be out of balance, starting newa new birth control, and other factors like stress, weight changes, or medical conditions can also affect how often you bleed.
When periods come more often than usual, it means that the time between one period and the next is shorter than what's normally expected. Your body works with hormones like estrogen and progesterone to control your menstrual cycle. If these hormones are not balanced, it can cause you to have periods more frequently. This can happen for a few reasons. For example, if you are under stress, have changes in your weight, or if you exercise a lot, your body might react by changing your normal cycle. Sometimes, underlying issues like thyroid problems or other conditions that affect hormone levels can also play a part. In college-age women, where their bodies are still learning how to balance hormones, it might happen more often. It’s a good idea to keep a record of your cycle and share this with a healthcare provider if you keep noticing frequent periods or your frequent bleeding starts to cause fatigue or dizziness, so they can help figure out if everything is working as it should be.
