I Was Pregnant In June And Aborted My 1 Month

I was pregnant in june and aborted my 1 month pregnancy through pills. My cycle was coming normal after that. Now I am again pregnant and I missed my periods on October and November. Its been 6 weeks. And I want to terminate my pregnancy can I still use pills for that or I have to operate this time. Please tell me I am really very worried about this l. Thankyou!
