I had un protected sex 5 weeks ago, I have been really moody and I keep getting dizzy, I also can't eat too much without feeling nauseous. To day it would be the day I would start my period but I have no cramps or back aches which is VERY strange for me and I'm only bleeding a little bit and the blood is the color brown. Could I be pregnant?

Take a Home pregnancy test... thats far more accurate and quicker than trying to decide if you might from symptoms.

You had unprotected sex, the possibility is there.

You could be pregnant, but it's really too early to tell. You will have to wait to see if your period actually comes first. If not, take a HPT using first morning urine.

TaraAnn19,

I welcome you to this beautiful site, first!

The signs you are telling and the symptoms your body is showing and the reasons you are describing, combined together compel me to wish you a happy pregnancy period of 9 months, or so! Nausea, no-cramps, bleeding and brown blood are sure-signs of what you FEAR, but symptoms are symptoms, after all, and the guess is guess, after all, even as this guess is not 'wild'. This is for sure.

You should however go for a pregnancy test, which is the acid test.

Nausea, no-cramps, bleeding and brown blood are sure-signs of what you FEAR,

They are also premenstrual symptoms.
