Everyday I feel tired and nausea. At night the nausea gets worse (With NO Vomiting) and sometimes I can't sleep at night. I had a light cramping and bad nausea last night, and this am. I've been off my period for 3 weeks now. And I've been feeling nausea, headaches, a tiny back pain on my lower right side, along with slight cramps. I took two cheap dollar store test. They are negative. I will take a first response test Friday. Wish me luck. But does anyone felt like this before?
