Can i get pregnant?

My last cycle was from December 16-22 , a day after I had sex I've been spotting up till now! I have been very stress since I had my period and my period was almost 2 weeks late. I've been cramping like I'm having ovulation but I keep spotting on and off. Me and my SO do have sex since my cycle ended and yes he does cum in me. Is there a chance I can still get pregnant?
