undetected pregnancy

I have been feeling the signs of pregnancy for about 3 weeks now. i have nausea, fatique, sickness morning and night. my belly is starting to distend outward. My urnine test came out negative twice but, the doc don't forsee anything wrong. They did take a blood test and i am waiting on the answer for that about 2 weeks ago my family practioner took a blood test and it came out negative for pregnancy. could i still be pregnant or is there another problem going on here?

Hi! If you have missed your periods with all these signs of pregnancy, and your second blood test is negative as well, then  other causes of delayed or missed periods will have to be looked at such as stress whether emotional or physical, hypothyroidism, polycystic disease of the ovary, pituitary tumors secreting prolactin, anemia and poor diet, hormonal imbalance, unexplained or sudden weight gain or weight loss.
If you have not missed periods, but have these signs of nausea/distended abdomen etc., then acidity, gastric reflux, IBS, Crohn's, pancreatic and liver dysfunction will have to be ruled out. Do discuss this with your doctor and get yourself examined. Take care!

I'm going through something similar right now. A couple weeks ago I had a hunch that i may have been pregnant. I took 7 tests altogether and 4 were positive. I went to the clinic we have and that test came back negative. It's been almost two weeks since then and I just took an at home text this morning and it was negative. I've been sick and I've noticed my lower stomach is bigger. I've been eating more than usual and I've lost weight. My boobs were sore for about a week but now they just feel heavy. I'm not sure exactly when my last period was, but im thinking the end of June. Anyone have recommendations?
