Concern first time mom. Need opinion

Jay

Hello ladies! I didn’t know I was pregnant until couple days ago. I found out I was 8 months pregnant. My concern is I got my hair done twice and got my nails done ( acrylic and all) at least 3 times and drink alcohol at least twice since end of January and a day before I found out I was pregnant which was on March 4. I wasn’t really expecting being pregnant. My boyfriend and I was on and off trying for a while now but since my mom recent passing I’ve been really under stress that’s why I didn’t even consider being pregnant when my period was late.( I have very irregular period btw it’s usually 34-45 days cycle). Should I be really concern about my baby in my stomach? I’m really scared I didn’t really probably took care of myself and I wasn’t taking any vitamins or prenatal. Please help. Give me your opinion
