Help!

So me n hubby have been TTC for four months. Well last month my "period" wasn't much of a period. It wasn't my normal. My moods have been terrible, light cramping, nausea, boobs sore ect. Well I was supposed to start my period Monday. I got some  light pink to brownish discharge Sunday and nothing else since. I'm a day late or so. My 20 month old daughter is clingy all of a sudden. How many of you all would guess I could be pregnant??? All these seem familiar to when I was pregnant with my daughter.
