Is this normal??

My cycles are somewhat irregular. I've been TTC for about a year and had two chemicals in a row but nothing since then. However, I am about a week (give or take a couple days) away from my expected AF. I have mild cramping...it feels like my period is coming but milder. My boobs are also tender. But these symptoms come and go? I FEEL pregnant...can't explain why. I took a test and it's either negative or vvvvvvfl. I might just be too early to test. Thoughts?
