Quoting Mom to one girl:“ I'm 3 weeks pregnant and already starting to show. Did this ever happen to anyone else? Do you think ... [snip!] ... could wear last week. Plus I'm 37 and there is a chance also of twins because of my age. Any information would be helpful.”
I thought I was having twins because I swear the same day I took the test my belly popped lol, you just start showing sooner with your second. You can take a look at my pregnancy album if you want, the first set of pics are of me pregnant with my daughter, the last several are me pregnant this time around.
