If the miscarriage
was within the first month, you sometimes only know by taking a pregnancy test and having it come up positive, and then taking one late
r and having it come up negative. Those early miscarriage
s are called "chemical pregnancies," and can be mistaken for a slightly late
or heavy period. If you have a miscarriage
in the first trimester, depending on how far pregnant you were, you might pass tissue or clots, and have cramping, and bleed.
