I've had Increased Appetite, Bloating, Cramps, Gas, Heartburn, Headaches, Dizziness, Cold/Flu-like Symptoms,Fatigue
, Vivid Dreams, Frequent Urination
, Backaches, Tender Breasts, Sore Nipples, Irritable, Bleeding Gums, and Nausea. But i've taken 5 pregnancy test and they were all negative and i've had my period every month but it's been irregular since August. Could this all be from stress or something else?
