Is this still a normal discharge? 8 weeks pregnant here

My apologies for the image shared. I'm a bit worried lang regarding my discharge. Pale yellow to light brown discharge madalas after magwiwi pagkagising sa morning. Then ganyan lang naman karami. Pero this past 3 days, consistent na light brown na watery ang discharge ko. I am taking Heragest once daily for more than a week now. I already consulted my OB and was scheduled for a visit on Monday. May mga same cases with me here kaya? Anong nangyari after?
