New mom, late period

Jassiel

Hi moms! I had my daughter two months ago through an emergency c-section but I was about 7cm dilated. Anyways! I got my period about six weeks after the c-section and it was heavy and painful. I’m a couple days late from my period, is that normal? I’m also breast pumping/feeding. The reason I’m a little concern is because my husband and I been having sex.. so is there a chance I could be pregnant again? Or maybe it’s just me? I am under some stress as well
