Brown discharge isit normal? Im at 6weeks! Its actually quite abit should i be worried?

I also experience some pinkish and brownish discharge on a few days between week 5 and 6. For the peace of mind, I just went to see my gynae at wk 6 and he prescribed me with Duphaston 10mg Dydrogesterone to take 1 tablet twice daily to strengthen womb. Since then my spotting have stop these few days 🤭
