Could I be pregnant again?

Trinity • We were going to have a baby but we had an angel instead. Carson Daniel; 11/12/17 💙 Baby L; 4/14/18

I lost my sweet Carson 11/12, here lately my boobs have been hurting so bad and I’ve had no appetite and some pain right below my belly button. What should I do? Could it just be left over hormones from being pregnant with Carson? I haven’t gotten my first period since yet, it’s due in 9 days.
