Could it be possible?

Had taken depo shot that is for three months on November 6, 2017. Worst thing cause I had long month period with one week break. Went to OB to stop my period on February 2018 and gave me pills it’s helped stopped my period. My body felt weak and lack of appetite so I stopped taking pills. I felt back to normal but with no period. No period on February and this month March. I feel my breast sore that woke up with pain and still since last week. On Saturday March 24 he cum inside me. Could I possible be pregnant? Of course we want another baby. No judge please

I will set up an appointment with ob soon.
