Ate, I know this is super worrying, lalo na yung brown discharge + dizziness combo! Since you're on Duphaston and your OB gave you a specific plan (PT after 10 tabs), I'd really suggest reaching out to your doctor ASAP para malaman kung normal lang ito or kung kailangan ng check-up, hindi na kailangang maghintay ng full 10 tabs if you're feeling off na. A few of us moms had similar situations and honestly, peace of mind from talking to the doc right away beats guessing, kasi the dizziness + brown discharge together ay kailangan i-check talaga, especially if you're worried about pregnancy or hormonal stuff. Wishing you well, and please don't wait too long to message your OB!
