Just worrying

Hi all,

I lost a baby this January and found out about 3 weeks ago I’m pregnant again finally. I guess maybe I didn’t notice symptoms as much the first time because I was on magical cloud 9 of nothing wrong will ever happen but now I find myself over analyzing every little thing. I’ve had random cramping on my left side nothing too painful ( it sometimes feels like a tingle) and sometimes some low back pain. I’m paranoid about an ectopic pregnancy. I’ve had no bleeding or anything else to indicate anything is wrong. Anyone else experience the same thing? I have an appointment Wednesday with my doctor for a prenatal physical and I plan to bring it up but until then any stories to make me feel less paranoid?
