Pregnancy Related. Continue with baby?

My wife is 5-6 week pregnant. Her last period was on 29th May 2018. This is our first time and 4-5 days before only we came to know that she is pregnant. But the problem is in month of June she had consumed many medicines such as "Rapeed D, Dipep, Sidoze, Colmint, Pantocid D" for Gas, "Sinarest LP" for Cold & Fever, Etizola 0.25 as Sleeping pill. She had consumed alcohol thrice (Bacardi Breezer - Rum punch contains 8% alcohol, Normal Breezer contain 4% alcohol, Absolute Breezer - Vodka punch contains 8% alcohol). Apart from this once she had consumed "Unwanted 72" pill within 20th-25th June. Now my question is, 1. Is there any side effects on baby due to the above activities? 2. Shall we go for abortions or shall we continue with baby? Please suggest what to do in this situation as we both are really confused now. Thanks in advance.
