Possibly pregnant??

TTC for 3 months now and the past 2 weeks Iv had almost no appetite. The past 3 days I have had light cramping and all of a sudden food isn't an interest for me and makes me sick thinking about it. Usually I eat 24/7 And my stomach makes noise cuz I'm hungry but I just don't wanna eat and Iv gained 5 lbs in the 2 weeks and my period isn't for another 2 weeks exactly. Is this a possibility I could be pregnant?? Currently 3 dpo also.
