It's so hard to tell b/c my period can be so inconsistent. I know last month is was later then I thought it would be. Probably about 4 days or so. This is a little strange for me b/c my period is always early if anything. I am opposite then the normal woman...when I was a teenager and in the color/winterguard my period actually increased. I was getting it every 3 weeks instead of the regular 28 days. I was very active and had almost no fat on me at all. My mom actually took me to the doc b/c she thought something might be wrong. They couldn't find anything. After I stopped being in the colorguard my period went back to normal.
I should really be getting my period tomorrow but I haven't felt any cramps or really bloating or anything. I'll be interested to see when it comes this month...hopefully it will (yikes!). This will be my 4th period since starting to OP...the first two months I didn't notice any difference, just in last months late period. I'll let ya know...
