Implantation bleeding or just random spotting

Angela

A few days back I wiped just to find bleeding like a period starting but nothing in underwear. Grabbed pads right away to protect underwear, though it was my period starting but then nothing. No abnormal cramping or other symptoms, I have chronic nausea and my breasts always feel full and heavy and sore at some times during my cycle so not unusual there. Has anyone had implantation bleeding with 1 pregnancy but none previous pregnancies? I have 2 living children and 2 angel babies (1 molar 1 regular miscarriage) and no other pregnancy have I had implantation bleeding. I did have a d&c 2 months ago due to extended miscarriage bleeding could that have increased my chance of implantation bleeding? Honestly at this point I just want to get my cycle or the positive this uncertainty is killing me
