Help, am I being paranoid?

Lauren

At about 5 weeks my nipples were sore, consistently thirsty, and I felt so tired. Those were basically my symptoms. Now at 7 weeks I have no symptoms except very very slight nausea if I don't snack every couple hours and still thirsty.

I have started having lower back pain and very slight cramps. My first prenatal appointment is on the 11th of January.

Should I be worried?
