Cramps 15 weeks pregnant

So I’m 15+3 currently with my second baby and I’ve been cramping quite a bit and they literally feel like period cramps. I remember cramping with my first pregnancy but it felt different, it was more like a stabbing stretching pain which I think was round ligament pain, but this feels like actual period cramps and I’m getting slightly worried. I was just wondering if any other mums are feeling the same and if it’s normal? I don’t want to bother my midwives if it’s normal, especially with this pandemic going on. Thanks!☺️
