When to start taking prenatal vitamins?


I originally planned to have an abortion(don’t hate on me you have no idea what I went through mentally) but I got to the parking lot and I just couldn’t do it.

Since I planned on the abortion I didn’t take prenatals. My LMP was March 1st. That puts me at 8 weeks tomorrow. I’ve read that people who don’t find out until like 10-12 weeks and their babies were fine.. I’m worried I might’ve caused something to be wrong with it
