Spotting at 8 w 5 days

Sudha

Hi, i had few un-noticeable amount of brown discharge at weeks 5 and 6 and my doctor monitored hcg and it doubled. I have my first scan tomorrow and this morning again I started to spot brown discharge. I am already on progesterone supplements as i had two losses in the past. This is making me nervous. Please help if any one had this kind of on and off spotting brown and still had a healthy term.
