White discharge is normal , however if it is itchy or foul smelling do discuss with your doc once . . I would also advice you to discuss the vaginal wash with your doc as well because v wash didn't really suit me and my doc recommended another one which did !! Joints pains are also common as Rebecca said you can use a hot water bag . . And also period like cramps are common during early pregnancy

White discharge is normal don't worry just keep the area clean and dry, use V wash.. if the discharge is too much then use panty liners. Keep changing your inners often. Joint pain is also normal use balm and hot water bag, mild abdomen cramps like period pain happens in early pregnancy however if its too much or accompanied by bleeding or spotting please let your doctor know.
