So I'm 9 weeks and probably the luckiest girl in the world because I've had very few pregnancy symptoms in regards to morning sickness. However over the past day or two I've had lower abdominal cramping. It feels like a 'pulling' type of ache but mainly stays on my right side, reminding me of period cramps a bit honestly.... Just not as strong. The other way I can describe it is like I just did a ton  of sit-ups ... But a little lower on my stomach. If these pains didn't feel similar to period cramps, I probably wouldn't worry as much. I know for a first time mom close to the end of your first trimester is when all of your muscles start to stretch and make room for everything that's growing and changing. Which I'm hoping is what this is.
