Does anyone know what this could be ? It just started happening today the last time I had sex was yesterday. I’ve had the same sex partner for a while now but I did have unprotected sex about 3 weeks ago . Could this be a std ? It doesn’t burn or itch & I just got off my period 2 days ago & my discharge is very watery when I woke up this morning a lot of it was dried on my leg hints to why I’m wearing this pad
