Frequent urination. This is a symptom of early pregnancy, and is probably due to a combination of the effect of hormones, increasing blood flow to the kidneys, and a slight decrease in the capacity of the bladder, as the uterus sits next to it and is getting bigger. If there are no other symptoms (like burning or pain on weeing, or obvious blood in the wee, which may suggest a urine infection), it is usually simply pregnancy related, and will often become less noticeable after twelve weeks or so, and recur later in the pregnancy when the uterus is bigger. It might cause women to wake in the night to wee, interrupting their sleep. It is also a nuisance at other times.
It is important for women to drink plenty of fluid in pregnancy, and the extra weeing this causes is often a disincentive. It is important to drink, however, despite the inconvenience. Perhaps doing more of the drinking during the day, rather than the evening may help prevent the night-time interruptions.
Swelling. Even in early pregnancy, women may notice fluid retention. This is related to the hormonal and blood vessel changes described already. Slightly swollen ankles, or a bloated feeling, or skirts and pants feeling tighter, or putting on a couple of kilograms in a week, are not that uncommon. In very early pregnancy they are usually related to fluid changes, rather than fat deposition. No specific treatment or action is needed for this.
