i had 3 days delayed in menstruation was my first sign. but i don't think i am pregnant coz i feel unhealthy and been stressed for a few weeks of sleeping late. if it is positive i hope it would be healthy pregnancy.
It could be a hormonal imbalance or something. I am not sure though. Take time like a week. If mentruation is not coming then check it with a pregnancy test. I hope its positive coz a baby is a blessing. :)
