My period is worrying me


I just got done with the weirdest period of my life. It was so incredibly light and the blood was all a dark brown color.

I normally have incredibly heavy periods and this wasn't even as bad as the first day of my period, which is normally already incredibly light.

I'm that I did something to mess up my system because I went to the doctors before my period started and they gave me medication for Chlamydia and I drank two glasses a wine a few hours after I took the singular dose.

I'm worried that something is wrong with me because this is just incredibly not normal for me.

Any advice/any thoughts on what might be wrong?
