Maybe someone here can help me make sense of this..

I’m 27 weeks with my first. Some days she’s super active and others it may only be once a day I notice her moving around and be able to see and feel her from the outside.

However, there will be multiple times a day that I feel a “thump” on the inside. I can’t feel it from the outside or see it, but I feet it internally. It’s usually down low near my vagina and sometimes my butt. Is that the baby moving? It seems like it would be to me, but I’m not entirely sure.
