found out I'm pregnant!

Yesterday I found out I am pregnant! It took me so long to find out if I was or not.. I had taken 8 home pregnancy test and one at the doctors and all of the came out negative.. so I decided to take a blood test last week. Yesterday they called me and told me the test came out positive! I'm nearly 12 weeks now and im just crazy excited because this is my first pregnancy! Any advise? Like what to do and and not do during pregnancy? Any important things I should know. I could really use the help. Thank you 🤗❤️
