AM I PREGNANT OR NOT?

Hi guys help please ... 

I had my normal December periods from the 4th to the 11th and then for the first time I had sex (unprotected with the pull out method - he did not cum inside me). I had spotting because I broke my virginity but then I got my periods again in December for the second time in one month from the 24th to the 30th. I was nervous so I did a pregnancy test on the 5th of January and it came out negative. I then go my periods for January from the 18th to the 23 and it lasted shorter than usual I then did another pregnancy test on the 26th of January and it came out negative. I got my periods on the 2nd of February and it lasted 7 days this time but I’m wondering if I could still be pregnant?
