Brown discharge during first trimester.

Last Thursday I did pregnancy test in home and it was positive. Little bleeding started so i went to hospital. Doctor did early pregnancy scan and said everything is normal. The next day bleeding started, there was almost half pad bleeding. I again went to doctor, she did some test to check whether fetal heart beat was present and found that heart beat was present. So she gave progesterone tablet for 2 times and asked me to come in Jan 1st week. But i could see that from past 7 days i am able to see brown discharge in my panty and when I go to toilet i could see Little brown discharge. Is there is any problem should I go to hospital or should I wait till Jan 1st week as i am already taking progesterone tablet 2 times per day. Kindly suggest me what should be done.
