Not knowing that im pregnant. I took several capsules of ibuprofen, paracetamol, amoxicillin. What are the possible deseases my baby could have?

Most Likely nothing! All the items you listed are fairly safe, but I strongly suggest before you decide to take any medications, you ask our doctor first!
No problems. All of these meds have been studied in detail & found to be safe in early pregnancy. Remember to check with the doc before you take other medications or herbal preparations from now on.
