It's time to see a Dr./Midwife. Although pregnancy test are highly accurate (even those purchased at Dollar Stores), there are a few women in the world who do not secrete enough pregnancy hormone in their urine to make it positive regardless of how far along they are. A blood test will give an accurate diagnosis of pregnancy for these women. Don't delay, see a Dr and find out what is causing your symptoms. You will likely need an ultrasound to find out why your abdomen is growing. Start with crisis pregnancy clinic or free women's health clinic if you need to, but please see a professional ASAP.
