Possibly Pregnant??

My fiancé and I are TTC and we've been having sex everyday since last Monday. With him finishing inside me every time. The last few days I've had cramping and very very fair sore breasts. Last night I had very very light pink spotting/discharge coming out. It's been very very light still today and my CM is egg white and it's lightish/medium pink consistency. This is our first time TTC so any feedback is good feedback. My projected period is supposed to start next Tuesday but is irregular! Thoughts? Thanks ladies!
