6 weeks late

I'm 6 weeks late. I have never been this late the most I've ever been late is a few days. I've been throwing and feeling nauseous ,my boobs are killing me. and I'm always hungry carving fruits.

But I took 4 test all negative. I dont know what it could be. I havent been stressed these passed few months have been a wonderful breeze for me. I haven't taken another test since I was 4 weeks late.

I'm waiting till my health insurance kicks in next month to go to the doctor.

I also haven't told my husband I'm late. I just don't want to worry him...But I don't feel right not telling him.

what do y'all lady's think?
