Stomach aches - tell me I’m not alone with this!

I’m 16 weeks tomorrow, is anyone else getting random stomach aches? Like sometimes all across the lower half just a dull ache? I don’t really know how to describe it, I’m not talking about the sharp round ligament pains. Assuming it’s normal as had a scan today due to a little spotting and baby was all okay. I feel like I’ve been getting these pains the whole pregnancy but none of my friends that have had kids know what time talking about. Tell me I’m not alone ladies!
