I'm 17 I do have sex I have this white sticky stuff that comes out it happens around my period and not also. Is this normal it doesn't smell. Could I have a std ? I take an oral contraceptive. I've had this for awhile I don't itch

Having a discharge before your period is normal, and if it doesn't have an odor or a colour like purple, red, orange or green, don't worry about it. Oh, you, it doesn't itch, that is good.

I hope you guys are using a condom.
