Newly Pregnant. Do's and dont's of 1st trimester?

Nicole • Happily married to the man of my dreams. Mom of 2 girls, Elena and Esme, and 3 👼👼👼 .
I just found out I am pregnant. I am only 4 weeks along. This is my first! My husband and I got married in January of this year and have been trying since! We finally were blessed with this baby! I will be 30 in a month and have been dreaming about having many babies. I'm so excited! It will be awhile before I meet with the midwife. But, what are the do's and dont's of the 1st trimester? What can I not eat or do etc. any advice would be awesome! Thank you!
