Wasn't thinking :( advice please

B❤
Earlier today I had a little headache coming on and just feeling a little blah. I was at my in laws and saw the ibuprofen sitting on the table and took 2 pills (200mg). As I normally would pre pregnancy. It just dawned on me now, 6hrs later I took that instead of Tylenol!! 😕 
Feeling so dumb for that. Do you think it could of done any harm? I go to the dr Tuesday for my routine prenatal appointment.
