There was severe cramping and some bleeding last night.

Although it was painful but it probably means that the medicine is taking effect.

Then this morning I found a round blood mass ( slightly bigger than a marble ) when I went to the toilet. It should be the yolk sac ( just called doc and she said it is not ). Cramping is gone. Bleeding seemed to have ceased. But why does my heart feel so sad?

Still worrying...hope the blood test n checkup nx mon will bring some good news.
