Hi, I Notice I Was Pregnant Around 20th Of Dec

Hi, I notice I was pregnant around 20th of dec 2015 cos I was suppose to see my period on the 16th of dec, I use abortion pills to abort but I didn't really bleed so I try it again 3 days after, I bleed this time around but is not as heavy as I think so I waited for 2 weeks to confirm if the pregnancy has really been terminated. Now am 6weeks pregnant in my scan result. Please can I continue with the pregnancy, I hope it won't affect my baby?
