too early to tell?

Hi! My husband and I had sex during my fertility window (about days 12-14 of my cycle and I have a pretty regular cycle), I felt a slight cramp on my lower abdomen like the feeling you get when you're about to get your period and i'm feeling slightly dizzy and feeling like my BBT is a little high than normal. My CM (cervical mucus) is sticky and resembles egg whites. Is this too early to detect if I'm pregnant?
