I think that everybody's body is different and different symptoms mean different results. Personally, I have had both happen to me. With my first pregnancy, my period was a few days late. I took a test, it came back negative. I still hadn't started, so I took another test. It came back with a faint positive. I went to the doctor, my blood tests showed that my HCG level was higher than normal, but not as high as it should have been. They did an ultrasound and I found out that I was pregnant. I only had symptoms for about three weeks after that and all of a sudden, they were all gone. About two weeks later I started spotting. I went to the ER and they told me that the baby had stopped developing two weeks prior to that and there was nothing they could do. Of course, I was devastated. But, my friends and family were very supportive. With my next pregnancy, I took a test and it came back positive. I went to the doctor and everything was as it should be. When I was about 8 weeks along, I started spotting, so of course I was sure that I was having another miscarriage. I went to the ER. They did an ultrasound and everything was fine. After that, everything was great and seven months later, I gave birth to a beautiful, healthy little girl. So, even though the waiting is horrible, just hang in there until you hear from your doctor. All you can do is pray that everything will turn out the way that it was intended. I will pray for you also. Be Strong!!
