My case was not a common miscarriage. My fetus could not be located, so they called it as 'Pregnancy of Unknown Location'. After observing for almost 2 weeks, the HCG level was unstable, sometimes it increased a little bit, sometimes it decreased a little bit, and I always had vaginal bleeding. So, the doctor suggested that I should take a MTX injection because they were afraid it was an ectopic pregnancy (宫外孕). I took the injection on Sep 1, 2010. I could not get pregnant within 3 months after the injection. In Dec 2010, I consulted the doctor in Government Hospital and also a private doctor. They said I could get pregnant already. But I and my husband decided to start trying on this cycle. Hope we all can get pregnant soon!!!
