Looking for some reassurance 😔

Last night I woke up to some pretty intense cramping, it felt sharp and stinging across my back and front (not like af cramp). I was really worried 😟. I went to get some water and I felt shakey and dizzy - I almost fainted and I had an elevated heart rate! 5 minutes from when it all started, it just stopped!

I have no spotting or bleeding, but with the intense cramp I had I was expecting the worst.

Has anyone had this?

I’m mostly worried about ectopic and spontaneous loss.

* I am 5 weeks and 5 days. So far I haven’t had any other crazy symptoms.
