What to expect ?

Brittany • Christian Mother , & wife ,baby number two Due march 27th??
Okay I have an appointment next week with my OB . I've only had one Pap smear and that was when my first pregnancy was confirmed . So i don't really know what to expect when I go in for a routine exam? Should I tell them were TTC , or tell them I had a faint positive test , will they do blood work ? I really don't know what to expect ..
