Maybe be really disturbing...

Me and my boyfriend have been having sex lately, a lot of sex. And from the times before I didn’t experience these symptoms and I’m kind of worried. This morning I woke up did my routine and I felt something coming down I immediately thought it might of been my period but then I remembered that it was impossible because I’m on birth control (Nuvaring). It turned out to be this white-ish and a tint of yellow discharge. I have no idea what it is the smell wasn’t bad. But I’m kinda freaking out because since yesterday I’ve been having some itchiness on my Vigina and it just feels uncomfortable. Any ideas what it is or might be ?
