How big were you at 17/18 weeks?

Hi guys! I’m currently pregnant and starting to show a little, but I’m naturally overweight so it’s not very obvious. We want to tell our families soon but both sides are traveling for the next month. When they return I’ll be around 17/18 weeks. For FTMs who are slightly overweight, did you have a noticeable bump around this time?

I don’t want my bump to be obvious when I announce as I want to keep some semblance of a surprise for both our families!
