It's too hard to say for sure. The best thing to do would be to get blood work done so you know for sure what's up.
my period was due on may 14th, it comes every month at exactly 29 days apart. and lasts 5-7 days. from march 9th my next period should have been april 11th and then may 14th. and yet no period yesterday or today.
It sounds like you might have lost it. The only thing I can suggest so you know for sure is to have blood work done, or try waiting till the next time your period is due to see if it comes.
it was about 5 days, it started with just spotting for the first few days dark brown old blood. there was 1 clot, so i got it out of the toilet (tmi) and looked at it, it was bowl shaped and about the size of a half dollar all one piece, after that came out i stopped bleeding. the blood was never the normal color of my periods. at the end it was bright pink but never red.
It might have been a chemical pregnancy. If you had a doctor, you can request blood work be done and it will tell you if you are still pregnant, or if you did lose it. The period that you did have. When you say light, how light was it? How long did it last. Was there any dark red blood or clots?
