medication and early pregnancy hypothetical question

So.... I wasn't thinking and took cough syrup, naproxen and strepsil throat lozengers for this nasty cold I have currently.... which made me feel a ton better BUT we have been ttc for the past couple months! Now I'm concerned that if we were successful this month and I am pregnant (we wouldn't know until later this week) that perhaps I have now potentially caused harm to the hypothetical baby?!! 
Someone please put my mind at ease!
