Abortion

I'm 5 weeks pregnant & I'm single I broke up with my ex in November 2019 I moved out the ending of February but I was still messing around with my ex. He already has 3 kids with his previous girl before me but I still dont want to be in a relationship with him anymore. now I dont know what to do if I should take the abortion pill or keep the baby. I live alone & I make just enough to support myself. I need some advice comments etc..
