Success with progesterone supplement??

I went to the DR the day after finding out I was pregnant since I’ve had hormone issues for years. They thought it was best I do some bloodwork because I was having intense cramping. They wouldn’t give me a whole lot of information unfortunately, but said my progesterone was a little low, so they put me on a progesterone supplement. I go back on Monday for them to check my levels again and see if it’s gotten better 😬😬 I’m terrified as my first pregnancy I did not have any issues like this! My first ultrasound isn’t for 3 weeks so I am struggling to not panic 🫠
