6dpo I think ?

I'm around 6dpo. I'm not 100% certain. I feel like I'm going crazy. I'm very very gassy and very bloated to the point where it's uncomfortable. I haven't changed much about my diet either. I don't eat out so it couldn't have been from fast food or anything. I've been having some pretty disturbing dreams in the past two nights. They feel very real and I wake up freaked out because they are just terrible dreams. I wake up with a very sore throat and sniffles. Also I wake up with abdominal cramps that feel exactly like AF cramps but I'm not one to get cramps before I'm due at all. Every night I get a decent amount of sleep and I still struggle to keep my eyes open during the day but I'm trying to not drink coffee just in case. I know it's suppose to be impossible to have symptoms this early but I just feel weird. Just like when I conceived my daughter.
