That would be very early for baby if you are a FTM, but not unheard of, so possible! Also possible that it's some funny gas (sorry , but true). I assume it wasn't painful?
Me: 35 year old FTM, a busy city banker living in London, and a constant worrier. My DH: French guy, car fanatic, best husband ever. Our baby boy: Due on 17 April, currently 37 weeks. I can't believe it - I made it to full term!!!! Last measurement: 3150 gs at 37+1! This is going to be a big baby
I am carrying very low with my second and at around 17 weeks I felt little jabs from the baby about where my zipper rests for my pants. My doctor said this is very common in second+ pregnancies. Otherwise with my first (and second) my pelvic area pops from any shift of my hips, due to the realignment. Maybe for you it could be one or the other as well?
