Delayed periods. Had cough. Took medicines. What effect will it have on baby if pregnant?

hello. Im dona..im not yet sure if im pregnant or not..2 weeks ago i took a pregnancy test (i was suspecting i was 2 weeks preggie) and got a negative result. i am still waiting for my menstruation for this month (it will come anytime soon, if not, i ll test again). I have had bad cough the past days and took ambroxol mulcosolvan(about my 5th day now), also took mefenamic(dolfenal) a couple of times I think when i had headache . my question is what would be the possible effects of those to my baby (that is, if i am pregnant)? thanks!
