Have you notices an frequent urination, lately? As early as 3 weeks (although typically closer to 8 weeks) following conception, you may be traveling to the bathroom more often than usual. Frequent urination is most likely due to increased blood and fluid levels in your body during pregnancy as well as your growing uterus putting added pressure on your bladder as your baby gets bigger. This symptoms tends to intensify as pregnancy progresses. More frequent urination could also possibly be caused by drinking more fluids than you typically do, urinary tract infections (UTIs) and even diabetes.
