Ok here Is my situation for the past two or three weeks I have a lump in my right abdomen like 2 or 3 inches from my navel and it feels swollen I have no severe pain its just an uncomfortable and sometimes every once in a while ill get a very vague pain and my bowel movements have slowed down a lot since I've noticed this I also get nausea when I eat sometimes at first I thought I could be pregnant but I have taken 4 hpt test and all of them have been negative and I got my period a couple days late but I got it and normally it last 5 days but I only got it for 3 days heavy flow and then on the 4th day spotting but I fiugured that was because I was so paranoid I was worried sick about being pregnant. What could I have ? Has anybody had any of these symptoms or this lump? I have also lost a lot of weight due to all the stress and loss of appetite. Any info will be greatly appreciated.
