Its scary first time around if you dont know whats happening, Grab yourself a pregnancy book with all the information needed in them. They were a great help for myself when i first got pregnant and pu tmy mind at ease.
Also you will need to start taking folic acid for the first 12 weeks of baby growing!
Also google what you cant eat when pregnant on google there is a ton of sites that can help with what foods to stay clear of!
Congrats on the happy news!!
