Scared to have #2

Kristen
I currently have a 9 month old baby boy and I've been having constant dreams about having baby #2. It's an exciting thought but scary at the same time. I'm 20 years old. Just looking for some opinions or your experiences with baby #2. I just switched from the depo back to the pill to get my period back on track but I already feel extremely nauseous it even wakes me up in the middle of the night. My husband and I always have unprotected sex other than my birth control.
