Okay so I was four weeks late on my period, and the last two days I have been on and off very very light spotting. The color is brown. And like not like the red brown that usually happens to a lot of people it's brown brown it doesn't look like blood really at all. It does but it doesn't. Me and my boyfriend had sex every day but two days last month and so far everyday this month. In June I didn't have a period at all. My periods are usually light and only a few days long.
