Help...ttc

I am a 7dpo today and I haven't felt like myself here lately. I've been extremely moody, I've been feeling more tired than usual. I've been having small cramps in my lower stomach. I've been feel sick to my stomach on and off all day, but I feel like I can't get enough to eat. My boobs are tender... And my nipples appear to be darkening.... Is this normal? Could this be symptoms of early pregnancy or is AF about to show? Has this happened to anyone else? If so did you get a bfp? Please help me...(learn more on Glow: https://glowing.com)
