I have alot of waswasas even about Allah and Prophet SAW. I was not religious and did not perform and follow teachings of Islam seriously. But I have been practicing Islam alot from last 6-7 months Allahumdulillah. After I started practicing Islam I have started to have a lot of evil and bad waswasas.

This is the Shaitan. You must seek refuge in God and ignore these thoughts and ideas. Don’t give up your hard work. Shaitan doesn’t want you to succeed. He will try everything. Surround yourself with positive people. Read about paradise. Stay away from haram as that enhances satanic thoughts
