Missed period?

Fiona • Live life to the fullest.
I got my implant taken out on 30th November and had my period on 11th December for only 1 day. Usually my periods last about 6 days. We have been having unprotected sex and my period isnt here yet. I dont know how long my cycle is so i dont know if im late or not? I took a test 3 days ago which was negative. I dont know if i should test again or wait longer?
