Didn’t know I was pregnant and drank and smoked

Omg I feel so horrible rn!!! So I have been drinking alcohol and smoking cigarettes like daily not to mention all of the stress I’ve been under with my fiancé. So about 4 days ago I was drinking a beer and I threw up and it was just a small one but I was like ig that’s normal bc beer generally tastes nasty and makes me gag every now and then the next day i was really weak and my stomach was hurting and I got nauseous eating my sandwich, so then last night I’m sleeping and I swear it feels like an arm or or leg rolled across the bottom of my stomach slowly from the inside and then today I poker it a little and I felt it again. Omfg I am so afraid to even test and if it positive the reality that I’ve been drinking n smoking while there is a baby in me inhaling all that n feeling that alcohol omg this is tearing me up I feel like a monster. I haven’t drank or anything since but I have to be far along to be feeling this if this really is a baby right?. I have a 10 month old right now. Has anyone ever been pregnant unknowingly and been in a similar situation, was your child healthy or in pain or got sick from it??!!!
