6 Frequent urination
Symptoms of needing to urinate frequently usually appear between the 4th and 8th week and then again in later pregnancy. This is due to the uterus becoming larger, and it presses against the bladder increasing the need to urinate. Likewise, hormone levels also increase the urination frequency.
In some cases, it may indicate a urinary tract infection, which is a frequent condition in pregnant women, but one that may need to be treated by a doctor. If you experience pain while urinating it is important to see a doctor.
