Hello, the problem is weight gain with big stomach and some breast changes. Some additional features like pains, cramps and "baby kicks".
Your age, personal history, menstural history and sexual history would be useful in helping you.
However, the good thing is that the ultrasound
scan has ruled out a tumour. So the next thing that comes in is a "pseudopregnancy" state. This is usually seen in stressed out patients who are under care for infertility
So do get back with these details so that I can help you.
