it happens to me so many times . r u close to ur dues date. i ve been trying too. u could or u could not.
I'm not sure either way I thought I was pregnant then got two negative test results then no period for two months.....I'm calling the doctor on Monday either way
it can be, but it can also be a sign of ovulation, hormonal fluctuations can also be the cause. are you pregnant or just hoping? if you dont know yet, try not to read too much into it, it can make you crazy ;) if you are worried about it see your doctor
