shortened period with Tri Lo Marzia

About a month ago I started taking Tri Lo Marzia, and I started what I think was my period about 2 days ago. I normally have 7 day heavy periods, but this time it started out super light only 2 days ago, and continued to be very light, and seems as if it's ended today. I just wondered if any women experienced the same thing with Tri Lo Marzia? Responses are appreciated, thanks :)
