Probably all in my head but maybe?

Okay. Hubs and I officially started ttc a week ago when he got back and the day he came back I was ovulating. So we had sex all during my ovulation week (as per glow) and half way through I started getting really bad cramps and even got a cold. Cold only lasted 4 days but cramps on and off. So now today I have cramps and felt nauseous for like half an hour and I also had heavy clear sticky cm.

Is it too early to show signs of pregnancy? Should I test in a couple days?
