I had my baby on June 15 and I didn’t had a period since I have birth. But also I was breastfeeding and bottled feeding too. Two weeks ago I had a spotting for two days I didn’t even fill a hole pad and than stop. Two days ago spotted again and yesterday when I went to used the restroom I saw a blood cloth size of a penny and that’s it no more blood. I’m actually more bottle feeding than breastfeeding. Should I be concerned?
