I felt like I popped with this baby one night last week - I woke up in the morning and my singlet I was wearing just felt tighter. I don't know if visually I looked remarkably different though. It has been more of a gradual thing to actually have the look of feeling pg.

Another contributing factor to you not having much of a bump maybe if you have good ab muscles. One of the reasons you pop out later in your first pg is because all your ab muscles can be holding it all in. Once bub stretches everything, you will get a belly, it might just take a bit more time.

Your 17 weeks now, I would say that in the next month you will probably start to look pg. I think most people start to look pg by the 20 - 22 week mark.
