Breastfeeding twins

Hello, I just found out we’re pregnant again. We’ve decided that we’re going to get a abortion because we just had a set of twins 7 months ago. Twins are expensive and we don’t feel like we will have time and energy for a new born baby(babies if it’s another set of twins, twins run deep in my family) . My question is, will getting a abortion affect me breastfeeding?

I’m only 5 weeks so I know they will give me the meds by mouth for the abortion.

Thank you
