Brownish discharge.

Hi mummies! Anyone experiencing brownish discharge during your 6weeks - 7weeks? Am having it now, went to the gynae and thankfully baby is okay .. HR 138bpm standing at 0.80cm .. how often does this brownish discharge persist and what is the next step that you mummies do? This is my 1st pregnancy so am a bit cautious. Nonetheless, i was calmed throughout the experience but I want to know if am not alone ..
