hi...i have the exact same symptom...the first time it leds to miscarriage...then 2nd pregnancy, it happens again and i took the hormome pills prescribe by doctor for 1 mth, and currently in my 20 wks...
take as much rest as possible and dont stress most importantly...when spotting appear, rush to kkh ane immediately and have the doc to assess, dont delay...according to my doc, there is nth they can do to avoid a miscarriage cause it was due to chromosome irregularity...
