I usually have regular periods and this one came five days early and has been lighter than normal. I am on day 3 and I still haven't experienced the Niagara falls I usually have on day 2&3. I have been sleeping quite irregularly for the past month or so because of being dumb and talking with friends till dawn a few days a week. I have also been quite stressed and possibly iron deficient. I wouldn't be worried if it wasn't for the fact that I had (protected, but still) sex the last day of my fertile window. Should I get a test, talk to my doctor or just relax and enjoy a light period for once?
