big belly?

Al

so once again my doctor isnt sure of how far along I am. he said he thought I was 21 weeks and 4 days at my last appointment I would be 22 weeks tomorrow but he said I was measuring at 22 w 4 d. so I could be going on 23 weeks tomorrow. but my family keeps asking if I'm having twins cause I'm so big already. this is my second baby.
