Having a yeast infection will not stop you from having your period. In Fact, many women are more prone to yeast infections before and during their periods because of the hormonal changes that occur at this time. In fact all of the nutrients coming from your uterus during your period could actually feed the infection and make it worse.
Unfortunately, a doctor cannot properly diagnose you with a yeast infection while you are on your period. If you think you may have a yeast infection, especially if you have never had one before, it is important to see your doctor. The signs of a yeast infection are similar to those of certain STDs (such as Chlamydia and gonorrhea) and other medical conditions – so it is very important that a medical professional assesses the situation and gives an accurate diagnosis.
TeenHealthFX recommends that you call your doctor to find out when you should make an appointment to come in for an exam. Your doctor will do a pelvic exam to look for swelling and discharge. Your doctor may also use a swab to take a fluid sample from your vagina. A quick look with a microscope or a lab test will show if yeast is causing the problem. A yeast infection will not go away by itself and does require treatment with antifungal medications. It is very important that you meet with your doctor so he/she can determine whether you actually have a yeast infection, and recommend a course of treatment based on his/her finding.
Many women who get frequent yeast infections treat them themselves. There are several OTC medications to treat them. However, you have to be familiar with the symptoms and medications in order to do this.
