Stressed out 😔

Nayab
So I got a BFP on the 14th of this month... Been feeling extremely gassy and bloated. Cramps came on and off . Today I had period like cramps... No bleeding or spotting. Lasted about 20 min. And then went away. Haven't gotten any more for the rest of the evening but now I'm not feeling bloated or gassy anymore either. My breasts don't feel as sensitive anymore....My appointment isn't u till January 5th.  I am thinking of going to the ER tomorrow but as of now I'm freaking out that something must have happened?! Please I need some reassurance that this is normal... 😭
