Anything is possible, and home pregnancy tests can be tricky.
One thing is for sure.. Because you may just be having nervousness and be stressed, which could also cause symptoms like nausea, cramps, sickness, weight gain, cravings, moodiness, irritability, things like that..
My suggestion, is to consult a doctor, and have a medical professional give you a pregnancy test.

We cannot tell you if you are pregnant or not. The only way to know is to take a pregnancy test or see an ob-gyn.
