What are the symptoms of pregnancy before your missed period?

It varies, you could have tender breast, nausea at the smell of certain foods or perfumes that didn't bother you before, you could have the dry heaves, you could experience dizziness, you could be thirstier than usual, you could be cranky and sensitive. If you think you are pregnant then go to OBGYN and get the test done there so you don't waste your money on a store bought. They can give false positive and vice versa and then you wind up going to Dr. anyway.
