Weird feelings after transfer

Hi,

I’m 3dp5dt, and since yesterday I’ve been feeling this fluttering / pulsating sensation in my lower abdomen, happens whenever I sit or lay down. It’s the weirdest feeling, because if I look down at my stomach I can literally see the pulsation (it’s super short but kind of frequent). Has anyone had the same?

I’m doing a programmed cycle with progesterone (suppositories + oral caps) and estrogen pills.

I thought it was just something that’s going to pass, but it’s been going on since 2dpt, and it kind of brings up my anxiety.
