paranoid

hey everyone. i’m a little paranoid here. i’m almost 8 weeks pregnant & i go to my doctor on Monday.

but i’ve had some lower back pain the past few days. it’s not constant, and it feels like period pains when it comes.

I didn’t find out i was pregnant for a few weeks so i was still drinking/hitting my vape that contains nicotine.

my boobs aren’t really sore anymore, but i do feel sick still here and there, mainly only when i think about food lol.

no bleeding or spotting.

is this normal?

ETA: I’m 23 and this is my second pregnancy.
