If your optometrist says you are a candidate for contact lens use and prescribes non-toric lenses that fit properly, you can use a 'normal' (non-toric) contact even if you have mild astigmatism.
That said, please be sure to have contacts fitted by a professional optometrist. Lenses that don't fit your eyes properly can cause damage to your cornea and overall eye health.
I use 'normal' (i.e. not toric) soft contact lenses and I have astigmatism of -1.0D in my non-dominant eye. Not having the astigmatism corrected by contacts hasn't been a problem for me.
In an eye with astigmatism, you will not get vision that is as crisp when using a non-toric contact. But if the uncorrected astigmatism is mild enough and doesn't cause you headache or visual fatigue, you may be able to tolerate it.
Most likely. Try the non toric lenses and see if vision is adequate.
