Went to the hospital last night due to my brown discharge.?

My cervix was closed and although the probe on the scanner was broken they where able to see baby heartbeat and movement. I think i felt my 1st flutter yesterday, felt like erfly's but did not last long, could it be baby? Im 15 weeks and 2 days Just so you no. So have seen heartbeat at 15 weeks and will hear it tuesday at the midwifes. The chances are good that my baby is going to be ok isn't it? Still have a little discharge that's an light brownish colour but doctor saw it and was not concerned
