Is this normal?

Hello everyone,

I am 30 years old and I have had my period since I was 10 years old. My fiancé and I have been TTC for almost two years now and as of today I am two weeks late. I have took three test so far and all negative. The first two test were taken on day 1 & 2 of missed period and the last one was taken on day 9 of missed period. I’ve also been experiencing motion sickness while he’s driving, slight cramping here and there, and really bad headaches. What is wrong with me? Help please!
