Could I be???

So my period ended December 23rd. I’ve had sex unprotected the 26th multiple times the 27th, 28th 29th, the 30th and the 1st of the new year! He cam in my every time. I’ve been having crams since the 28th now I woke up this morning with my body aching and like a kinda sick feeling. I already have 2 kids and when i was pregnant with them I knew I was. I have a feeling I’m pregnant again is it possible???
