Sleeping on left side making a shift in my body shape?

Hi mummies and experts, I read that pregnant mums are encouraged to sleep on their left side. I'm starting my second trimester and have been sleeping on my side early into pregnancy every night (using a maternity long pillow). But over time, I found that my body is oddly distributed: more lob-sided on my left side with a small bulge of flesh? Not sure if it's due to the position of the fetus or my shifting organs. So I look like a mild 'S' from the front with that tiny bulge. Wondering if mummies out there also experience the same?
