Needs help!!!!!

Last week my 4 year old daughter got really sick and I took her to the dr. She was really sick and didn't want to get on the scale. Being the mom that I am, I jumped up on the scale to show her there was nothing to be scared of. I'm 26 years old, 5"2' and at that visit I was 116 lbs. A week has passed and I'm gained 10 lbs. My now husband and I have been trying to have a baby. At this point in my cycle it's still to early to take a pregnancy test. Is this a sign that I could be pregnant or is something else going on? PLEASE HELP!
