I feel pregnant, I have big belly bulging out, i feel some sort of movements, I went to do two intrevirginal ultra sounds and they show my womb empty. My belly is growing bigger and bigger and my breast are sore. And I feel movements at times. NOt like kicks but light movements. My stomack feels heavy like a rock is placed there. I also am very tired all the time, and my lower back is hurting (which are signs of pregnacy because it was like this my first pregnancy too) and also my veins are greener and my hands are more pinker than usual, meaning there is more blood pumping around in me. Also I feel light headed at times but have never fainted yet. I don't have morning sickness but in didn't have it either on my first or second pregnancy.

I went to my doctor and she did pregnacy test and it came out negative, but my stomach keeps growing and its growing fast, not like slow. I am fasting so i know i am not eatihg alot, and i am still gaining weight. I am starting ot think i am going Crazy. Please help with any advice. I got checked with my blood, vitamins, thyroid and all is normal.

Could i have a baby growing outside my uteruous? is it possible? and would this explain why i am still menstruting even though its very light periods?
