What are these pains?

👏🏼👶🏼Amy👶🏼👏🏼

Sooo ladies, I'm 30 weeks today and since about 12:30pm I've been getting sharp pains in my cervix area. This is my second pregnancy and couldn't be any more different from my first, including a Low-lying placenta this time around so don't really know what to expect. Any ideas what these pain could be? They've been coming and going no matter is I'm sitting/laying or standing. Any advice would be great.

Thanks ladies&bumps
