<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi i need some advice im am month late on my period.. and i did a online pregnacy test thing and it sed im very high chance of being 7 weeks pregnant .. i have no signs of coming on my period.. i did a pregnancy test two nights ago and it came back negertive.. help x  <response>: HI, I understand your concern. Signs of early pregnancy like nausea, vomiting, giddiness are due to intolerance of increasing levels of pregnancy hormones Few ladies can tolerate them very well do not have any pregnancy signs except delayed periods. Now about your confusion about pregnancy tests- - I feel the tests done by yourself are more reliable than online test. - to confirm remove the confusion, you can get USG abdomen done. Thanks.
