First time mom!!!

AF due the 25th, felt very “off” so I took a test I had laying around and was not expecting this!! My husband and I have been trying to conceive for 4+ months so I am over the moon!! Any tips? I am a step mom to a 1 year old little boy who has been in my life since he was 2 months. I know the basics of taking care of a child... but carrying one.... I want the best for my baby. I am super nervous but like I said, very blessed and excited!! Thanks in advance for the tips!!!
