Im 8 weeks pregnant,but before i’ve learned im pregnant i suffer cough allergy and running nose, so i take vick 44 plus syrup and robitussin DM syrup , but its not affective , so i take mucobron forte 3 x a day for 5 days , and citirizine 1 tablet a day for 10 days , does it effect my pregnancy , i didnt go to a doctor yet because im scared.now im experciencing dark brown spotting for 6 days,but i didnt any pain .
