I need help // what the hell is going on dOwn there

Basically since i came off of my period i’ve had an extremely sore downstairs area, it’s been itchy, tight and really painful. i’ve been getting a clear almost crusty discharge and the material of my underwear looks like it’s been bleached, the colour has lost. I know it’s nothing to do with what i’ve been wearing.

This hasn’t happened in the 5 years i’ve had my period and i’m really concerned. Its my first period since becoming sexually active so i don’t know if that affects anything.

Please help it hurts when weeing and moving.
