I haven't experienced much of a period this month yet, according to the calendar I should have start 5 days ago. I had some light spotting that lasted about a day then nothing. I have irregular periods and if I'm stressed sometimes skip them, but I haven't felt like I have been stressed lately. Nothing in my life seems to be different that would cause me to skip it. However, I'm not on birth control and my boyfriend only pulls out. I took a pregnancy test and it was negative, just wanted to hear what your alls opinion is.
