4. Thick and looks like jam with clots
Jam-like blood discharge during your period with dark red clots means that you might have low progesterone and high estrogen levels. Most of the time, it does not mean anything. However, if the clots are large in size and there are many of them, it may mean you have a hormonal imbalance. Also, fibroids in your uterus could be the cause. This condition should not scare you though.
