I Had An Abortion October 17th And Had Unprotected Sex

I had an abortion October 17th and had unprotected sex the 26th of October and the 2nd of Nov. i took a test last thursday ( oct. 10) and it looked like there was a faint line but very noticeable, today i took another one and there was a faint line but way more light, is it possible it was sort of positive bc i had a n abortion, or can i be pregnant bc i had unprotected sex after my abortion?
