First time TTC...

I have an 8 year old son and a 3 year old daughter. Both of whom were complete surprises. Therefore, this TTC thing is all new to me! Plus, I have a terrible memory and can't remember pregnancy symptoms from my first two...

My left breast is tender (for some reason, the right is not following suit), I've been cramping on and off for a few days, my lower back hurts like crazy, I've been eating like a pig (which is not AT ALL normal for me), my normally terrible sense of smell has been working far too well, I have been unexplainably exhausted and my face is super broken out (I NEVER have acne). I took a test this past weekend and it came out negative.. But, I'm beginning to think I tested too early...

Any of y'all have the acne as a symptom? I feel like that's the only one that's really abnormal...
