So I am

6mpp I have had about two periods since my baby was born. One in October and another in December. However I seem to be spotting a little. I spotted after one wipe like February 13th. Wiped a couple times and I didn’t have any more blood. Now Wednesday I spotted a little and after a few wipes no blood. Today I spotted a little and not any blood on the pad again? So it started the 13th of feb and I didn’t fer it again until March 3 pretty. However I have been having cramps for like the last 5 days and feeling tired, dizzy, and nauseous. I don’t know if it’s just pms or what. I need to note that the blood only comes out of my vagina after a bowel movement. So it’s like old blood from near my cervix that only comes out if pushed out during a bm. Is this just post partum spotting or could I possibly be pregnant again?
