Yep you're right!! That's your baby moving and you can see it from the outside!!
I experienced this for the first time about 4 nights ago!! I was sitting still watching my belly for about 10mins waiting and waiting and then it happened and I saw this little bump in my skin pop up! It was the BEST thing ever!! I hope DH sees it with me next time....

DH and I have felt our baby from the outside with our hands for the last 2 weeks it's very exciting.... ENJOY!!

Sometimes my baby is really active in the mornings, other times really active in the evenings!! Today, bubs is sleeping ALOT haha

I reckon 20 weeks onwards is the best part of pregnancy
