Is it possible??

Ok, I've a total of 8 pregnancies which have included miscarriages, one still birth at 5months (preterm labor), and 3 living children. This is hopefully going to be our 'rainbow baby', kinda dislike that term for some reason but any way....I'm petite and my first 3 children I didn't start really showing till I was in my 5 month but my last baby (our angel) I started showing quite early around 14 weeks. I am 9wks6days and I feel like I'm already showing. Is this possible?? In my case being really petite and no, I'm not over eating and I don't feel bloated at all.
