Are you pregnant? I only ask because your last sentence makes it sound like you're not sure lol
A peachy colored discharge could mean slight blood tinge. Could be normal, could be not. It depends on if you're pregnant, and if you are, how long it lasts, how much of it there is, if you're experiencing any cramping or anything, if you've had sex/an internal exam/vaginal ultrasound recently, and if it gets worse.
Basically we need more info to help you out lol
Yes fist time being pregnant
