5. Late Period
PMS and pregnancy have the symptoms described above. How do we then tell one from the other? One of such signs is a missed period. If you have had no periods for longer than usual yet have experienced the symptoms listed above, then you should take a pregnancy test.
6. Cramping
Cramping is another sign that is typical of both PMS and pregnancy. It is hard to tell which of the two cases is yours unless you take a test.
