You sure could be. Some women get pregnant quickly after giving birth as their hormones and body are ready to go! I wouldn't guess from symptoms though (changes in breasts are also common after child birth due to hormonal fluctuations). You are now 4 days late. Can you go get a test to check??? Let me know! Would you be stressed being pregnant again so soon? I have boys that are 15 months apart in age. I made it work. :>))
