Hi, it is normal for female s urinate a lot before thier periods. Frequent urination can be one of symptom of Premenstrual Syndrome such as PMS. Increased urinary frequency by the increase of body fluids such as blood and other fluids. Fluid retention is one of the most common symptoms of Premenstrual Syndrome. So it is normal to have more desire to urinate just before menstruation. When the uterus enlarges it can put pressure on the bladder making you feel like you need to pee more. Some women also have water retention and bloating before their periods starts meaning they will pee a greater amount whilst menstruating. The main hormone in the second half of a female s cycle is progesterone. One of progesterone’s jobs is to retain water so that if the female become pregnant she will be ready to maintain a placenta too. When she doesn t turn out to be pregnant and the hormone levels drop there’s a lot of extra fluid to get rid of. As a result the female will pee more often. Hope this helps. Untreated pelvic inflammatory disease may cause scar tissue and collections of infected fluid (abscesses) to develop in your fallopian tubes and damage your reproductive organs. Complications may include: Ectopic pregnancy. PID is a major cause of tubal (ectopic) pregnancy. In an ectopic pregnancy, the fertilized egg can t make its way through the fallopian tube to implant in the uterus. Ectopic pregnancies can cause massive, life-threatening bleeding and require emergency surgery. Infertility. PID may damage your reproductive organs and cause infertility — the inability to become pregnant after one year of unprotected sex. The more times you ve had PID, the greater your risk of infertility. Delaying treatment for PID also dramatically increases your risk of infertility. Chronic pelvic pain. Many women with symptomatic pelvic inflammatory disease develop chronic pelvic pain that may last for months or years. Scarring in your fallopian tubes and other pelvic organs can cause pain during intercourse, exercise and ovulation. so before you plan for a child you have to take treatment for PID.Thank you.
