TONS of movement today?

Kira • TTC 1st for 15mons and I finally had my BFP!

So normally I feel baby movement first thing in the morning, some later in the afternoon, and the most later at night. But today he has been nonstop since 5pm. Like really big movement all over the place. Sometimes it even feels like it’s happening at two different points on my belly. Any reason why he would be extra active all of a sudden? Also I’m 28+3
