I'm 9 dpo I have been having pinching like sensation in my sides when I lay down. One night I layed on my left side and started feeling mild cramps that lasted all but a minute. I started a headache about 5 dpo off and on I usually don't have headaches when my period comes. I have cold like sytmpoms stuffy/runny nose, drainage and sneezing plus tired but can't sleep at night. I'm constantly hungry but really don't have an appite. Last night I got bright yellow discharge no smell, ictching or burning when I pee it was just there when I wiped. I am getting for urine track infection but this is the first time I've seen yellow discharged. Could I be pregnant.
