Large clot?

Amanda

I'm 5 and a half months postpartum. My periods have been regular and have been pretty much the same as my pre-pregnancy periods. Today, however, a large clot ended up on my pad. Please excuse the tmi pic, but I am concerned! I know the hospital told me to be on the lookout for large clots in the first month or two after pregnancy, but what about 5 months after? Is this something to be worried about, or is this just the 'new normal' for my postpartum body?
