Movement?

Skye • I’m an Army Veteran and so is my husband. We have a 5 year old and due with our second May 23, 2018. My little family is so excited for the baby ❤️😍👶🏽

I’m 18 weeks tomorrow but lately I have been getting pressure in different parts of my lower stomach for a couple minutes then it goes away for the past like week. Could it be baby or something else?
