"Beta HCG, the same hormone detected by pregnancy tests, plays a role in increasing blood flow to the kidneys. Hormones like progesterone and relaxin are also involved in increasing filtration by the kidneys," said Ashley Parr, a specialist obstetrician and gynecologist at MemorialCare Saddleback Medical Center, California, quoted from Parents.com""

"Starting around 10 to 12 weeks, the uterus has grown to the point of exerting pressure on the bladder. This restricts the bladder's capacity to hold urine, which also leads to frequent urination," said Ankita Langan, MD, an obstetrics and gynecology specialist from Novant Health in North Carolina."

In some conditions, these symptoms can sometimes be a sign of something more serious. "Frequent urination should be known because it can be a sign of underlying medical conditions such as urinary tract infections or even asymptomatic bladder infections. This condition can increase the risk of normal pregnancy and should be addressed immediately," said Kyle Graham, MD, obstetrician and gynecologist specialist.

"If pregnant mothers feel that the frequency of urination is very disturbing and accompanied by symptoms of fever and pain, consult a doctor immediately. There is no need to delay or feel ashamed. Tests or laboratory examinations are needed to determine the main cause in order to obtain appropriate and effective treatment. So, it's not always normal, moms. Source: Parents"
