Is my IPhone 5 hacked

Long story short i was surfing the web on my safari and this link directed me to an another as you know those "free sluts in your area hook up links" and the other way I could get out of it was to press yes and then I could freely move out again. Thing is, last night at 4am i changed my pw and logged out of every social network just in case and ever since that incident, my phone has been alot faster in terms of responding speed to like touches and ***. However my email is a little slow on getting and sending mails and i want to know if something did happen because of that link.

I would just restore my phone that should help!
