Hello
I don't know why no one has answered this for you and ill do my best to help. You could very well be pregnant and if your having sickness all day which a lot of girls get then i would go for a pregnancy test its confidental at any doctors office you go to or if you have the money you can go buy one. When i became pregnant i had my regular cycle then my next one two weeks later was only a day and a half long instaed of 6-7 days, whicj is when i knew i could be pregnant. Any time you have a different kind of cylce more heavy or lighter, it could be something, or it could be because your are stressed out maybe?? And if your having it two weeks early, since that was a sign for me i would get tested asap, if it comes out negetive and you still feel you might be pregnant test again in two weeks when your regular cycle comes, because when i tested the first time it was neg then two weeks later mine came out positive, so it may be too soon.
Well i hope ive helped and let me know how it went, feel free to add me as well.
Take care.!!!!
