Now, that's not to say these theories are always correct. In fact, there are several studies online that show that there were no demonstrable increases in thickness in women with thin endometrium who were given baby aspirin.
However, there was an increase in implantation rates in the aspirin group, which can't be a bad thing, considering baby aspirin is also considered beneficial to those of us with a history of stroke and sludge blood.
My pill box is now overflowing with theories. GO TEAM EGG!
