Light period than normal

Casey

Hey girls! So I started my period three days ago...usually I have some significant cramping and heavy bleeding at least one day of my cycle. This has not been the case, it came without warning, the tiniest bit of cramps that lasted no longer than a couple minutes and I haven’t filled a tampon this entire time. In fact, not even halfway filled a tampon....I do have PCOS but have never experienced this. Thoughts? Could it be possible pregnancy? Help! 😩🤔
