Weird pains in rectum

I am 5 weeks and 4 days. Today I have been noticing weird “gabbing” like pains that shoots down my rectum. It lasts a few seconds, then goes away and then I feel fine. Is this normal? And what could it be? It almost feels like a pulse of pain that shoots down from deep inside to my anus.... sorry TMI. No bleeding and very mild period like cramps on and off as well. I’m sure it’s normal but I can’t really find anything on “doctor google” explaining it. Haha
